Ford Ranger / B-Series :: Starts But Pressure Would Immediately Go Back To Zero When Shut Off
May 29, 2014
Got a 1986 Ranger 2.3 EFI 5 speed that I have owned since it was almost new and will never let it go. 290,000 mls and still running strong "except". Noticed the last couple of months that when I start it cold it fires right off. If I start it hot it always takes 3 tries and always goes on the third try except....on occasion it will not start at all. It is random and after I let it cool a bit (about 30 min) it will start. Over the years I have replace many of the fuel system components (fuel tank pump, high press. pump, inline filter and canister filter, fuel press regulator) but wondering what else might be the problem.
I put a pressure tester on it the other day and when I selected the key to start the pump would spool up to build pressure and shut off. The press gauge would register that but the pressure would immediately go back to zero. After start up it would hold a constant 30psi at all rpm,s. Shut the engine off and pressure drops right down to zero. Shouldn't the system hold pressure for at least a while after shut down? Could this be the problem with my sluggish starts? What would be the normal fuel pressure? Can't seem to find it in my Haynes manual. Once running it runs great.

I just rebuilt the carb on the truck, it has the 2.8L, and when I went go go start it, it cranked for awhile until fuel filled the bowl, then it started and revved up high, I shut it off immediately and it turns out the throttle linkage was binding for some reason, I fixed that but now it wont restart.
I was cranking it for a while and gas started spewing out of the top, so I took the top of the carb off and reset the float height and now it doesn't spew gas.
I pulled the plugs and checked for spark and it's a really bright blue spark. I'm thinking it's just flooded, lots of gas on the plugs? I'm just waiting for it to clear out now and trying to brain storm what could be wrong.

2000, 2.5L standard transmission. IAC replaced about 2 years ago, DPFE sensor and vacuum hoses replaced early last summer. Truck has been running just fine until I washed it last night. Went to work, and when coming to a stop and pressing in the clutch, engine starts to race without coming back to idle. Had to turn the truck off in order to get the engine from racing. Same thing on the way home. What else can/should I be looking at? I did not open the hood to wash the engine off, so it can't be water from the wash.

1996' Ranger with 183,000 miles. 2.3 cyl., Automatic, XLT
When I am driving and get to the 35 to 60 mph range, my trucks transmission wants to upshift, then immediately downshift to the gear it just left. It goes back and forth like this till I get where I am going, or after about 10 miles it will stop doing it. I checked the transmission fluid, and it is full and still pink.
I took it to Advanced Auto, and it blew a code of ECL Bank 1 I believe. I looked around the 'net and I think it came out to be the front O2 sensor may be bad/going bad.
Last week while it was warm enough I was driving with the rear window open, and noticed the faint smell of Rotten Eggs (this has been the only time though). Today I drove about 50 miles and basically used a quarter of a tank of gas. I am wondering if the catalytic convertor may also be going bad?

I was messing with the battery in my 200 Ford Ranger the other day and must of arc something. I know this because after plugging my battery back up my radio fuse was blown and my alternator was killed. I replaces the radio fuse, that works now, and got a new remanufacted alternator (tested mine at Advance it was dead). I installed it and nothing changed. The battery still wasn't charging. I know the battery is good because I tested it at Advance Auto. I took the alternator back and the shop replaced it with another remanufacted one. Same thing, installed it and the battery doesn't charge.
This time I took the alt back off and had it tested at Advance. The alt was dead. So I don't know if the part store gave me TWO bad alternators or if my truck is killing them. I find it hard to believe it could kill them immediately but my automotive knowledge is not that vast. I took the second (third counting my original) dead alternator back and they gave me a brand new one no extra charge. So I don't want to put a brand new alt in my truck and it kill this one too because I doubt they will give me a fourth one. What is going on? Could it just be as simple as I got two bad eggs?

I have a 98 f150(4.6 V8) that has 'seemingly' overheated for about 5 seconds twice in the last month. I noticed the temperature gauge went all the way up after about 1 mile of travel, then it immediately fell back down to normal. The truck has 198k miles.
I flushed out the system using a Peak Flushing Tee, replaced the thermostat with spring facing the engine block, and refilled the system.
I haven't had another overheating instance but I am having problems with my heater....the truck seems to warm up fine and the heat starts off working well. The temperature gauge reads normal for a few minutes then drops and I lose the heat. The truck blows cool air for a while, then will start blocking hot air again.
I believe the water pump has been replaced fairly recently...the pulley has no slack and I don't see any leaks or wetness around the pump or its weep-hole.
I read it could be a blend door or blend door actuator. I don't hear any funny clicking and obviously get some heat.
Should I try another new thermostat? Intermittent water pump problems?

I have a 1987 jeep cherokee with inline 6 and multi port injection.
Sometimes this vehicle only starts when hot
Some times only when it cold
I have recently fixed the fuel leak.
When its hot or cold and not starting if i relieve the fuel pressure at the fuel rail, in most cases it will start immediately. However if fuel pressure relief does not work. I disconnect the vacuum line at the what looks to be the EGR valve or the pressure regulator at the front end of the rail, then usually starts right away.
I have not tested at this time to see if the fuel pump is failing nor have i tested fuel pressure. I am trying to narrow down the problem to one specific part. There is no problems with cranking. There is spark - coil, plug, dist cap have been replaced.
It seems the problem is with fuel delivery of sorts. It was mentioned that sometimes the heat from the engine could be heating the fuel rail to a point which turns the fuel into a gas not allowing it to atomize.

I have a 92 ford ranger. About a year ago it shut down on me as I was pulling out of a parking lot. I replaced the Cam sensor which IS NOT located on the engine block by the fire wall. It is located on the front of the engine just above the primary cam which is just above the crank shaft and its sensor. It fired right up.
Then the oil pump went out and I just replaced it the other day and the pressure gauge/needle went past the half way mark even at idle. I drove around a bit, maybe 10 miles, then got in it to go to the gas station and got about 50ft from the house and it just died again and will not crank back up.
I am thinking its that darn cam sensor again. But, just like the oil pump was, it's a pain to get to and replace. How to test it. Oh, it is a 2.3 4 cyl. double overhead cam. I do have fuel pressure, I checked that already.

1987, 2.9 ... I got all my wiring repaired and replaced both the intank pump and the high pressure pump, for a few days it would fire right up as soon as you hit the key but it had a miss (the pumps shut off after a second or two with the key on "RUN"). I tore the throttle body off and cleaned all the carbon out of it, when I put the throttle body back on I noticed that the engine to body ground was loose so I ran a new piece of 4ga from the intake manifold bolt to one of the master cylinder bolts.
After I did this I went to start the truck and no go, the fuel pump turns on with the key but then it wont shut back off until you turn the key off. if you try and start the truck it will crank but wont fire, after about a half hour of cycling the key and cranking it will start to put a little bit then a few tries later it will start but sounds rough when it first fires. I thought it may be a stuck injector so I ran some cleaner through the Schrader valve on the rail. Still have nothing, both pumps do run but still don't shut off after a few seconds like they should and now it wont even try to start.

88 ranger. 2.9L manual. Just bought this truck. It ran great when I bought it. After a day or 2 it would idle rough. Almost die but it wouldn't. No check engine light. It seemed to do this intermittently. Some times I'd start it and it be fine. Other times I'd start it and I'd expect it to die at each stop light.
Now for the last couple days it dies on every start up. It won't idle. It'll start right away and then die. I can keep it going by keeping the engine rev'd but the check engine light is one. If I keep it running and start driving down the road it'll drive with the check engine light on for about 5 minutes. Then the light goes out and it runs like normal, even at idle, until I shut it off. Then it's the same story at next start whether it's right after I shut it off or hours later.
It doesn't seem to matter whether the engine is hot or cold. When the check engine light is out, it runs great the rest of the time whether at speed or at idle. To me it sounds like a sensor is on it way out. I figure if it was vacuum, it happen at every idle, and if it was fuel it happen all the time or at least every idle. Tried to get a code at parts store but the reader wouldn't work. It couldn't tell it was plugged in the the truck for some reason.

1999 ranger 2.5L.. I cranked it up. but it starts to die out. so when i give it some gas it stays on but it runs really rough (obviously). it shakes pretty nice. but as soon as i let off the gas it dies out. I am guessing its either air or fuel related. Any takers? Where should i start?

I have a 2005 ranger SOHC 4.0 new rebuilt engine It starts then dies after a few seconds then doesn't start at all unless it sets for a few hours or over night and will do same thing. It has 60 psi on fuel rail, good spark I'm starting to think my PCM is causing all this?

I have a 1999 ford ranger 2.5L. When I turn the key to the ON position, right before the ignition turn, everything comes on like it's supposed too. However, if i try to change into reverse, the truck will start without me even touching the key. Also, if I start it using the key and try to go into reverse, the starter engages and makes the all to familiar grinding sound. I am completely stumped.

I have a 95 4.0 EFI inside of my 83 Ranger. Once the motor warms up, it starts to have an idle issue. I have to press the gas, in order for it not to cut off. Here is a video I posted a while back. A person suggested that it could be the MAF needed to be cleaned. I did that, and it did not work.

The truck started acting up while driving. It would shut off (no miss or anything), but would start again. Now it is sitting in the driveway and wont run more than 3 seconds. The fuel pump has been changed and did not work. The fuel pump relay is new and did not work. I read that the fuel pump goes to another circuit after start up. Could it be running to start and then shutting off? Inertia switch is not tripped. Where to look next. 1992 Ranger 6 cylinder ....
