Why does it shut off with 50 psi fuel pressure.


Do you smell fuel? It may be flooding itself to a stall. After the stall the fuel settles back to the tank, plugs are drying and working again and you restart.. Look into the ignition, fuel /air mixture

My 95 ford f150 runs great till it warms up it seems then the fuel pump looses power n shuts down wait few mins kicks back on runs fine till few min later


Sounds like your ignition module it is common on fords to do this when its cool it will start and run fine but once it heats up the truck dies until you let it cool down again and then your up and running till it heats up again. Some modules are mounted on the fender others are mounted with the distributor have it checked and let me know how it went.

Quits after warm up wont restart


sounds like you have a fuel pump problem, fuel pumps will usually get hot and then shut off allowing it to sit 30 mins lets the pump cool down allowing it to start pumping, the way you can test it is get a can of starting fluid the next time it quits raise your hood and spray some fluid down into the throttle body and if it starts and then dies it is most likely your fuel pump, hope this helps.

I have a 1990 Buick century, that will not start, i have changed the ignition module, fuel regulator, plugs and wires, fuel filter. When changed the fuel regulator it started and ran great, shut it off and...


Sounds like your fuel pump is weak so i would check the fuel pressure first.The fuel pressure should be 40-47 psi with key on and engine off and 31-44 psi with engine running.If its not within these specs then replace the fuel pump.

Check for fuel pressure, 2.5 is Key on engine running

3.3 engine is 40-47 PSI (Pounds per Square Inch) Key on engine off
31-44 PSI (Pounds per Square Inch) Key on engine running

Idels ok, and when problem started noted after 5 min driving...now sooner...not till 25mph now at slower speed...it seems to build up to a back fire , cough/sputter...lurches, it bogs down some then...


check fuel pressure it should be 9-13 psi with engine running.You will have to remove fuel filter and install a fuel pressure adapter part #TA37650 to be able to check pressure.

1993 dodge caravan 3.3 v6 on days when outside temps are higher than 70 degrees after driving for a while if rpm's get below say 1200 car will stall out and after 20 mins. it will restart but will stall...


What does it do, if you try to accelerate when this starts to happen? If it dies,sputters or is sluggish, I'd start by changing fuel filter, and if that doesn't help, have fuel pressure tested when (if at all possible) this begins to happen. Had similar problem, winter was fine, hot weather it would die, and restart after 20 minutes or so, then go a fair distance again, then same thing. Fuel pump was on it's way out and when it got hot, fuel pressure would drop. First thing in the morning when fuel in tank and pump was cool, ran like a charm, but on way home from work, after sitting on a hot day, fuel got warm/hot, and pump heated up and that's when it started. Carried a fuel pressure gauge with me. Fuel pressure when cool, was 49 psi, and when it got hot, eventually dropped off to 2 psi. Sat for 20 minutes, jumped back up to 49psi, took off for home,then would eventually get lower and die again. Changed pump and filter, all was well. Try filter first, you have nothing to lose, and it should be changed if pump replaced later anyway.

Fuel pressure intermittently drops causing sputter and die.


check for 12v constant at your fuel pump if you are not getting that replace your relay.
if you are getting 12 volts at your fuel pump the fuel pump is possible to run tuel it gets warm then shut down to a lower rpm I would then replace the fuel pump

Car shuts off when getting up to running temp.


All I can say is that I had the same problem. It turned out to be a Temp problem with the distributor.

Here's what I did to catch the culprit.I started it and let it run in the yard. Then I took a hair dryer and applied heat to various components. When I got to the distributor with the hair dryer, and left it there for a few minutes it sputtered and stalled. I then applied some ice cubes in a towel to the distributor and it started right up. Replace the distributor with a junk yard distributor and it ran several more years.
As a retired electrical engineer, my theory to what happened is this. as the temp rose one of the transistor leads inside the transistor lifted off its connection and broke the circuit when I cooled it down with ice it made contact again.

The tough part of this is to isolate the problem.

Good luck, Hope this helps Loringh
