1988 Ford F350 won't start

Truck stalled driving down the road. When it cooled off it started and drove again a short time. Now it will not start. Replaced the fuel pump with no luck. Truck is getting spark. Cleaned relay switch connections. Wondering if it is a relay switch or fuel pressure switch?

I had trouble like this with a 1991 fuel injected version of this engine. It was an intermittent problem and the relay could be re-energized temporarily by turning off the ignition and restarting. It was a fuel pump relay that needed to be replaced and has been ok for several years now.

U will need to get the fuel pressure checked to confirm it is or isn't the problem, there is no substitute for proper testing work if u want to repair the truck in a min of time and a min of money spent on un-needed parts.

1988 ford ranger 2.9 ltr engine stalls while driving , restarts in a few minutes usually


There are several possibilities, but based on how you described the symptoms I suggest a profile igniton pickup. On these systems the failure usually begins as dropping a cylinder occasionally,like a misfire,mostly during high underhood temperatures,will manifest into stalling and finally into a stall with no resart condition. Symptoms are most likely to occur in summer. The pickup is inside the distributor and the distributor must be disassembled to install it,the trickiest part being the removal and installation of the distributor drive gear. They are iron and easily broken. The simplest solution is another distributor. The ignition modules typically do not fail in this manner,but this is classic for the pickup coil. A code for loss of pip signal should be present, it is possible for a code to not be present,though very unlikely. Having worked on these systems for years this would be my first area of diagnosis.

So I bought a 1988 Ford F 250 from a friend who drove it for a few years before he began having problems with it. The truck will start and run for about 15 minutes and then dies as if it is out of fuel. ...


Try replacing coil. Ford coils are notorious for issues. Common issue when coil gets warm, oil in coil expands and leaks upward into coil wire shorting out. When it cools down, starts right up again until warm. Note: This MIGHT be your problem - it does happen.

Does it have a carburetor or is it fuel injected? In 1986 it could be either way. It sounds like a carburetor with a choke problem.

F350 2000 stalling and sputtering while driving after running a while or runs fine


Many possibilities:
Is it a Diesel?
Camshaft position sensor recall may cover it.
Gas or Diesel:
Fuel Pump and/or relay.
Fuel Filter.

Engine codes could help if Check Engine Light is on.
