Lumina :: 92 Chevy Euro Has Spark But No Injector Pulse
Jan 19, 2015
Was called today to look at a car that wont start its a 92 Chevy lumina euro with the 3.1 v6 automatic 4 door. The car has a new crank sensor recently installed ran well for a while and now has no injector pulse. Checked for spark its good. sprayed starting fluid in the intake and it fired for a second acted like it wanted to run and then died. Checked for fuel at Schroeder valve it has fuel there I don't have a fuel pressure gauge but it sprayed pretty good. I'm not real good with electrical but thought maybe the ICM under the coil packs could be bad I have one off a running engine on my shelf but wanted to see what other people had to say first.

I have a 2005 ford ranger, 4.0 auto, 4x4, 60psi fuel presser, has spark and injector pulse, will try to start if you hold the throttle a little over 3/4 the way down, but will not fire on starting fluid.

I've got a 2001 4.6 F150, starter spins just fine, but it won't start. Checked all the basics, but it has no spark, and no pulses at the injectors. Is the PCM dead? Wore out the Haynes manual on this one....

I have a Chevy lumina Euro 3.1l from '92. I have a little problem with it:
My temp gauge, in the dashbord, says the engine is getting to hot. When the car is in idle, the temp gauge will just keep rising to around 190-200 F, when driving 2-3 miles, it will keep going up to 260 F and the heat indicator will start flashing.
When we measure the engine's temperature with a IR thermometer at the thermostat house it says 180 F, so the thermostat and the fans work just fine. (the fans kick in when getting over 180)
We have tryed replace the temp sensor twice, but getting the same result/problem. The problem just came out of nowhere.

I have a 02 venture with the 3.4L. No injector pulse when no start. Security system seems to be working properly. Just changed the crank sensor behind balancer and still does the same thing. No trouble codes present. Just not sure what to check next.

My friend like to get his 1990 740GL back on the road. It starts and dies. Narrowed it down to injector pulse. Noid light is bright the first couple pulses then gets weaker and weaker while cranking to almost nothing. Tried a new radio suppression relay.
Tested the voltage to the positive side of the injector plug and it is full voltage with no drop from battery voltage. I tested the negative side of the injector plug for resistance to pin 19 on the ECU and it was perfect no resistance. I thought that was a pretty good sign the ECU was bad. Replaced it. Jetronic and same exact number. Same exact symptoms. I checked the grounds on the valve cover to firewall and the ground on the intake from the harness.
What else could it be?The ECU I replaced is in the passengers kick panel. Is there another computer for the injectors?

I have a 1999 chevy lumina 3.1 with only 317,000 mi. and running strong. I had put new plugs,and wires about 6 weeks ago. The other day it started misfiring and I could smell the gasoline. I checked the tail pipe and it showed black smoke. In addition I put a piece of paper on the tail pipe and I could feel the misfiring with a consistent rhythm. I notice that it is running flooded(like if a fuel injector is not working correctly.) I cleaned the throttle body, checked all the coils and the spark plugs and they are good. It does not show any check engine light on. What could it be?

So about 3 weeks ago, I was driving down the road at about 55 mph, on cruise control, when my car just started slowing down. I looked to see all of my dashboards lights on and I realized my car was not running. I shifted into neutral and the car started right up again, but when I pushed on the gas it just kind of stuttered and shuttered before dying again. When I came to a stop, again the car started right up, but repeated the shuttering and hesitating when I pushed on the gas and tried to get going again.
So, I repeated, but this time i just pushed very gently on the gas, getting up to between 5-10 mph before the car died again. At this point, it just stopped running completely. The engine would turn over, but would not keep running. When I got it into the shop, the mechanic said they put a fuel pressure gauge on there and the readings indicated that there was plenty of pressure, no problems the fuel pump or lines.
After further research, the mechanic said he thought it was an electrical problem, that it could be the crankshaft sensor or the ignition switch module, but he just did not really know for sure. I had him replace the crankshaft sensor, since it was the cheaper part, and it didn't fix the problem. So now I am just kind of stuck on what to do here.

A week ago, driving home, the tech started to drop quickly to zero then recover, like the ignition was turned off and then back on. I was able to make it home. The car was due a tune up. I replaced the crank position sensor (OEM), replaced sparkplugs (Autolite Iridium), air filter, fuel filter, no luck. I ohmed the coil packs, secondary resistance showed good, replaced the ignition control module (aftermarket). After this, engine would stall after it was at temp, could restart, once put in gear it would stall, but I could go in reverse and drive home backwards.
Reinstalled original OEM ignition control module. Towed to GM Dealership, mechanic said fuel pump was bad, ignition wires needed replaced, one injector ohmed bad. I took car home, replaced fuel pump (OEM), ignition wires (OEM), no luck. Removed plenum, found pcv valve clogged, and hose kinked, replaced both, ohmed all 6 injectors, 5 injectors read 12.3 ohms, 1 injector was 11.6. Replaced all 6 injectors, (Napa), plenum gasket, still same problem.
GM dealership said computer said no data, they though perhaps ignition control module was bad, but I don't think so. I hooked up my Actron shorting plug, reads code 12 which means no faults, no other codes. I noticed EGR valve has a lot of carbon in the hole, thought about changing it, but I'm really not sure where to go now. The car is a 1994 Chevy Lumina with 230,000 miles, spent about $500 the last week doing brakes, and trying to fix this engine. Where to go from here.

This car started to stall sputter. I replaced the ignition module and it worked for while then nothing at all but still cranks. I checked all of the fuses and every thing was working. What I have found and i think this was the whole problem. The wiring harness that goes from the ignition module to the crank sensor, the wires were twisted and frayed and most likely grounding out on the frame and making the computer to shut down. So far after replacing the wires it started right up. Have not had a chance to take it for a test run to re learn the computer because my brake line busted.

My brother's 1995 chevy lumina 3.1 engine has been dying while braking for a stop and while reversing. Has replaced fuel filter, map sensor, throttle sensor, o2 sensors and still no change. He says he doesn't believe a tune-up is the cause either.

I have a 99 Chevy Lumina. The car periodically flashes the low coolant light. I check it and its fine. I don't know if its related to my recent problem. A couple of days ago, my car wouldn't start. All the lights and stuff come on, but there is no clicking or even trying to start. I kept trying. It wouldn't work. I left it alone to make some phone calls. I messed with it again after a little while and it started. It has been running until today. It started, I got my son to daycare. Then when I tried to start the car to leave, it did the same thing again. I let it sit for a couple of minutes and it started again.

Last winter, my car sporadically stopped while I was driving slowly or while I was standing still. I usually turned the engine off and restarted it right away without a problem. It happened a few times and then it stopped. This winter, it began again - frequently. I realize now that it only happens during the cold months.

1995 Chevy Lumina 3.1L Sedan with ~182K mi
Over the past 6 months, I have noticed fuel odor just about any time I turn off the vehicle, and I am also experiencing progressively higher levels of fuel tank pressure each time I remove the fuel cap. The fuel tank pressure seems to be greater the lower the level of fuel in the tank whenever I remove the cap. 6 months ago (~Sept) it was only a slight "hissing" periodically when removing the cap to fuel up, but now it occurs at every fill up and seems to have enough pressure to push the cap entirely off had I not been careful to slowly loosen the cap to relieve the pressure.
The entire fuel pump and sending unit assembly in addition to the tank and filter were all replaced about 4 years ago in May 2010 or about 28K mi ago. The issue has just come up progressively over the last 6 months.
Today, I inspected the evap. emission components and lines from the tank to the canister to the purge solenoid mounted on the rear of the engine. All lines are connected and seem to be in operable condition. The line from the canister to the purge valve mounted on the engine is completely free with no obstructions. I blew out the line with compressed air and absolutely no exiting particulates were observed. The lines on the bottom of the canister did not show any signs of wet fuel and there were no carbon particles present in the lines from what I could tell from disconnecting and inspecting. The vapor line from the tank to the carbon canister is not kinked or pinched in any manner.
I believe there is a fuel vapor check valve that resides inside the tank connected to the fuel pump assembly/sending unit. This was all replaced as a single unit as mentioned above. I am thinking this check valve may not be functioning properly and not allowing the vapor to escape into the carbon canister. I tried to apply slight pressure and vacuum on the vapor line connected to the check valve on the tank but no air was able to move in or out even with the gas cap off. However, I do have a full tank of gas right now, so I imagine the check valve will be closed.
The check engine light is not on but since this is an OBDI vehicle I am not sure there are any evap. emission codes anyway.
How can I test the gas tank vapor check valve? How can I test the vapor purge solenoid located on the rear of the engine? What malfunctioning component could be causing the excessive fuel tank pressure.

How do we activate the rear fog on the Tiguan? I have been playing with the coding but have as of yet found a way to activate it. I am assuming that it will be one of the lights on the hatch that is supposed to be the rear fog...but can not find or get any info.
I have the parking lights active already...now I want my rear fog active as well. I don't care about the dash icon...but I do want the light to actually work. I have done this on all of my previous cars (run the wiring etc) but this Tiguan seems to be eluding me! [IMG] [URL] ....
