I have a 2003 audi a4 1.8t Quattro. The car will only start if I jump the starter solenoid and will only run for a few seconds and shut off. I have a new battery in it and a few relays.
View 2 RepliesI have a 97 F150 w 4.6L engine with auto trans which I bought new and has approx. 150,000 miles on it. Very recently it would crank and crank and not start or sometimes would start. In searching through multiple threads on here many of the Ford techs recommended replacing the IAC valve as a cheap and easy to do fix and I did that. The OEM factory IAC valve appeared to be dirty with black soot. I also cleaned the MAF sensor in the air filter snorkel. I also replaced my very old battery at the same time. I verified that the fuel pump was running for about a second or two and shuts off after the ignition switch was turned to ON so the fuel pump is running since I could hear it. I replaced he fuel filter several years ago so it should be OK and not plugged.
I had to use starting fluid after the battery replacement to get the truck running but after I got it started and I did several driving cycles over three days to make sure the truck computer reset properly and the truck was running fine and starting without a problem. I was checking the starting every 4 hours or so for the first two days and it would start on the first crank every time without a hiccup.
This morning on day 4 when I went to start it the same problem occurred where it would crank several times and not start. I loosened the filter snorkel up and shot some starting fluid in there and it cranked up after a couple of tries and ran fine all the way to work. It seems like I have a fuel delivery issue of some type. I know the fuel pump is inside the tank and very expensive to replace if it turns out that it needs replacement. That is definitely beyond my capabilities. I plan to check the fuel pressure this weekend when I have a chance and can rent a gauge from Autozone.
My question is this: If it turns out to be a defective fuel pump can I just add an inline electric fuel pump outside the tank and have it pull through the tank in the pump leaving the in-tank pump abandoned in place? Are there any other sensors or parts I should be checking for voltages, resistance, etc. that would affect fuel delivery for starting? The truck seems to run very well with no misses of any kind and accelerates nicely after it starts. Also, no "Check Engine" light at any time and the bulb is working since it lights up momentarily when the ignition is turned to ON position.
Update Saturday June 25 - Got a fuel pressure test gauge and got the following results after installing a new fuel filter:
1. Bled off fuel pressure to connect gauge and after 5 or 6 Key On, engine off cycles the pressure came up to about 38psi and truck started up fine after pressure was at 38 psi. The pressure built up slowly after the bleed off with each ON/Off cycle and that is why it required 5 or 6 cycles to reach 38 psi.
2. Key ON, engine idling maintained 31 psi
3. Key ON, engine revved up slightly maintained about 31 psi and seemed to stay there even with more throttle increase.
4. Key ON, engine idling, disconnected fuel pressure regulator line and pressure increased to about 40 psi and stayed there
5 . Left the gauge connected after turning off engine. Key OFF, engine off, after 1 min fuel pressure increased to 33psi. It is about 90 degrees in the shade here today.
6 Key OFF, engine OFF, after 2 min gauge read 33 psi, after 5 min increased to 34 psi, after 15 min decreased to 33 psi, after 30 min decreased to 29 psi, after 45 min decreased to 26 psi, and after 60 min decreased to 23 psi. The pressure seems to decrease slightly with time which I think is what it is supposed to do. Is the pressure decrease rate too fast or about right?
The truck seems to be running fine and starts up immediately after sitting for a few hours but I am making sure to turn the key on/off for at least one or two cycles to build up fuel pressure and the truck starts every time for the last week. Does it seem like my fuel pump is OK or not? Fuel pressure regulator OK or not? Any other diagnostic tests I should run?
Recently replaced alternator and battery (was told by Brakes Plus that was the issue). The car (with no warning) sometimes just won't start. Whether after driving it or if it's been sitting for a day or two, sometimes it will only turn over once, but never start. Not sure if it's a timing issue or an issue with spark/fuel. There's also a loud click in time with engine rotation when it does start, may be an injector, also not sure with that.
View 4 RepliesI have a 2003 Volvo XC90, 2.5T AWD ... Since two weeks no start, no crank, when I turn the key in the ignition nothing happened, only the navigation screen is going off. I try the second key and it is doing the same. It happened when battery goes very low.
I try to scan it with different scanners and the same DTC is showing: (ECM-720A: Immobiliser communication)
Someone said I must remove the ECM and the ECU, read the both and use "Volvo Synchro V1.4 Loader" synchronize and program the key but i do not really know how to do it. Is it possible to do immo off ?
The VIN number is: YV1CZ59G741071108
My 03' Passat 1.8 won't start. It turns over and cranks. When I'm doing that, all the lights on the dash flash off and on (including hazards), the overhead light flashes and I can hear a click, click in the same time as the flashing. Seems like it must be some sort of electrical problem. Maybe a bad relay or fuse.
View 1 RepliesI have a 2003 vw golf gti. and It will crank but it wont start. I recently replaced the fuel pump and the relay.
There is no voltage at fuse 28 so I jumped the relay ( using both big pins ) and still no voltage at the fuse. however when its jumped the fuel pump actually runs. Still nothing
I am beginning to think it may be a spark issue but the fuel pump doesn't make a noise unless the relay is jumped.
So she will crank all day but no start. Theft light is going nuts like I am trying to steal my own truck!! I've read it could be a PATS issue.
However after I unplugged my pos batt cable and hook it right back up she starts like nothing ever happened.
its only happening every once in awhile. but it does get old. I have been just leaving my pos cable off whenever I shut the truck off.
Took my dad's snailblazer (trailblazer) since the 4.2 i6 in it gets better mpg than the old worn 5.4 in the f150. Well I didn't leave much gas in the 30 gallon tank about 1/4 tank or 7 1/2 gallons. My dad took it to the gas station on Friday and filled it to 3/4 of a tank. Got back in the truck and attempted to turn it over and got nothing.
Battery cable was a bit loose from what he told me, so he tighten it up. Nothing. I know the fuel pump is still going cause when you turn the key forward you can hear it whine. Starter is only a few years old maybe 6 or so. Not sure if that went bad or something else.
Last time something similar happened the A/C compressor seized up and wouldn't allow the engine to turn over. Well we eliminated the compressor around '09 and bolted a pulley in its place. Off the top of my head I can't think of anything that would have seized up causing this.
I'm working on a 03 Toyota matrix base 1.8. it died on the road and now will crank and sputter a little but that's all. its getting good spark, not sure about injector pulse but I do smell fuel after cranking. I have also checked the timing chain it is tight but didn't try lining things up to check if it skipped. Seems to have good compression but didn't have a gauge on me. Also tried adding fuel and it wouldn't kick off of that. I'm thinking crank or cam sensor but don't have a scope to test and don't know how else to check them.
View 10 RepliesCar not started for 5 months. 50k actual miles. Battery dead and replaced. Engine cranks but will not start. One squirt of starter fluid into air intake and it started immediately. Stopped and started several times (without starter fluid). Drove around block. Stopped and restarted with no problems. Let set for 1 hr. Started but ran only a couple of seconds and died. Will not restart but sounds like it is trying. Did not try more starter fluid again. Checked computer codes and none found. Can hear fuel pump run a few seconds when key turned on. Gas tank almost full but no gas added since last time it ran. Sounds like it is not getting gas?
View 9 RepliesI have a '99 F-150 with 4.6L V-8. The truck has run perfectly since I bought it a year ago. My grandson took it a short distance to a neighborhood store, and when he got back he parked on the neighbor's lawn.
IMMEDIATELY after turning it off, I told him to move it, and it would not start. Wouldn't even turn over. I did a little research, and replaced the most likely culprit, the starter....no change in condition. When keyed to start, the dash lights up, but that's it! I did get under the truck and there IS voltage getting to the large power lead.
The starter has it's own solenoid, however there is another one mounted to the firewall. Does this have anything to do with the starter?
My 1999 F-150 is having an issue after a tune up; changed coil pack, plugs and wires. It started and ran fine before, but after the tune up it doesn't even crank, just clicks and clunks. I hear a whine from the alternator, but last I checked (a couple days ago), it tested fine so I dunno if it went bad.
I thought it was PATS, but the theft light turns off when the key is in the on position and the fuel pump primes. I dunno if it's the battery, but it tests out OK with my voltage tester (12v+) But it may not have the amps required.
If the coil pack isn't grounded right, like if the platform it's on is corroded, would that cause this issue?
I left my F150 to sit over the winter parked near my house. Battery was bad when I went to start it a few weeks ago. Got a new battery, threw it in, but still no start. It wouldn't crank.
Went to work on it today and the battery was totally dead, took it to schucks and they said it was bad. So I got it replaced with a fresh one and I'm still getting the same thing.
Turn the key on and accessories come on, turn it all the way and nothing happens, except for the aftermarket radio turns off. I replaced the ignition switch last year. I tore apart the dash to see if that went out again but it looks fine.
What should my next step be?
My 1995 Audi 90 Sport needs to have the acceleration pedal pushed very far, about half way, before the car begins to to move, also when the pedal is put all the way to the floor the vehicle only goes to around 70mph. And finally I am having trouble finding a shop book for the vehicle.
View 7 RepliesI have a 2003 Grand Caravan, 3.3L, 75,000 miles. The van suddenly will not attempt to start. The strange thing is that when the key is turned to RUN I cannot hear the fuel pump. The normal 2 or so second on growl at the initial key turn is not there. When turned to start the clock on the radio goes out and no crank. I have found that the start relay is not passing on the signal to the starter. If I jump across the two pins going to the starter, the starter cranks fine. The van will still not start because I believe it has no fuel,due to the fuel pump not running. I thought first that it must be the neutral safety switch but does that have any control of the fuel pump also? I have found that the neutral safety switch requires that I remove the valve body for access.
View 14 RepliesThis has happened 3 times now in the last couple of months. After driving on wet roads, our 2003 Mazda3 won't start. It won't even crank or turnover (primary vs. secondary ignition). All of the other electronics come on when you turn the key, but nothing from under the hood. After a while of presumably drying out... anywhere from 15 minutes to hours, it starts again. I'm thinking something is shorting, but what.
Mechanic can't figure it out... but he's only had it for a day, and it's been dry, and starting fine.
My Daughters jetta will at time no start after it has been locked then unlocked. She told me that if the car doesn't beep when locked she sometimes has the problem.
The dash will light but no crank at all. Could this be an alarm issue or something else? I
2003 Pontiac grand am 3.4 car cranks has great fuel pressure and spark will not start when ambient temp under 75 deg without hot shot then fine the rest of day..have replaced fuel pump map sensor cam sensor air temp sensor.
View 1 RepliesI have a 2003 Pontiac Grand Am, 3.4L V6. The engine runs perfectly as long as it is kept hot. If allowed to cool completely it will crank and crank all day but never fire. However, if I disconnect the battery for at least 30 minutes and reconnect it, it fires right up every time. I have good fuel pressure when it will not fire, but it seems as if the injectors will not fire. Suspecting the injection driver, I replaced the ECM/PCM. The exact same problem still exists.
View 8 Replies I was driving down the road and suddenly lost tons of acceleration power had to almost flour it to move at all so I pulled off the road to stop and check it out. After I stopped I couldn't get it to start again it would crank like it wanted to start but nothing. So I had I towed home and it sat for a little while and then I tried to crank again, and it started and idled like crap and when I pushed down on the gas pedal there was no reaction, rpms didn't go up or nothing but still would idle like crap.
Symptoms stayed the same for about a day and no I have a crank no start. So then I did what little I could do just to see if it was an easy fix I changed the ICP sensor, IPR sensor, and EGR valve needed to be replaced so I replaced that too. Headstuds and gaskets have been done as well by previous owner but not I think it might be an HPOP problem? I am unable to read codes at the moment as well just FYI. Could this be a fuel filter issue even tho the secondary housing fills with diesel?
I am having problems with my truck not sure where to start. It was my everyday truck until one day I got ready to leave for work and the truck wouldn't say anything. It was getting power but no crank no start. Called tow truck he checked battery said that it was good. I got home tried to start truck and it started. I drove to the store and it did the same thing no crank no start. It has 110,000 Sigle cab manual windows...
