Question about 1988 Ford Mustang

1 Answer

Car dies when it hits 140-150 degrees

Just got this 88 5.0 lx conv. The car runs perfect until it quits running. It had one owner never wrecked 5 speed. It seems to run fine until it begins to warm up then poof, dead. At that point it will not recrank. After an hour of cooling it usually will start. The complete distributor assembly/sensor, fuel filter, have been changed. Still looses fire when warm. Did find one relay on the pass. fender that had a couple baked wires. Took and heat shrinked those wires and replaced the relay.By distributor sensor I mean the gray module on the outside. This 88 is air density computerized. Please give me the magic fix! MAP sensor, bad Ign. switch? please help.

I would replace the TFI ignition module and or the stator, these are the most common issues, you didn't say whether it had a loss of spark or fuel pressure, so just going on my 20 years of Ford dealer background.

My 90 olds cutlass supreme 3.1 automatic starts and runs until it warms up.reving the motor and letting it return to idle a few times,the idle gets ruff then dies and will not start again until it cools...


you most likely have a injector breaking down which is causing the quad driver in the computer which control the injector pulse to shut down .When a injector resistance is to low this will happen the correct resistance in ohms is 12.4 per each injector .This was a very common problem with 88 to 97 gm cars.have this zcheck at a reliable shop :)

Runs 5 minutes then dies. Won't start until engine is cold.


Try the WD-40 spray in intake of throttle body with air intake hose off, to see if it will kick at all, even for a second or 2. We need to confirm whether your losing fuel or spark when it dies. Ignition & fuel, can cause similar symptoms in this case.

89 thunderbird - 3.8 Car dies


i had this problem on my 88 t-bird 3.8L. not exactly sure of the cause but to remedy mine... it seems the computer was not telling the fuel pump that the car was running. so the fuel pump would quit pumping. run a wire from your battery to the positive line going to the fuel pump (temporary). if this solves the problem (and you don't mind solving it this way) make the wire run clean and hook it to a switch so you can turn it on when you wanna drive. this is not the way a dealership would fix it but its also not gonna cost you more than you probably have invested in your car. hope this helps

Engine dies at 150 degrees.


sounds like its not accident related, more like a idle air control motor or something of that nature, ive also herd of this happening when the crank sensor is going bad, it warms up and starts missing the signal.

Maybe bad Power Stage/Inquiry:driving down the highway at @ 60mph with 1/4 tank of gas in 100 degree temp inwell kept 84 760 Turbo; car just dies, engine turns over but will notstart] [Response:] Well, when my '84 760 Turbo died for no apparentreason as you describe, it was in the freezing dark, going over Donner Pass.Everything on the car worked except no spark and the engine wouldn't run. It turned out to be the ignition module, which is mounted on the inner driver'sside fender well, above the battery, close to where someone else mentioned theballast resistor was located. It's easy to get to and replace. Ifthat turns out to be the culprit, shop around before buying the new part. Volvo dealers charge several hundred $$$ for this thing, but I found one froman independent parts distributor for about $90 - the identical part madeby BOSCH with the same part number on it.
