Hard warm start
Hello! I’m new to the site and need your help. I recently purchased a 1990 F250 5.8 351 Windsor that was a farm truck. I got it for $300 and it ran and drive and just needed some love to make it the awesome truck I have always wanted. I have replaced almost everything and I am still running into a warm hard start issue.
here is a list of everything I have replaced:
-Alternator
-Starter
-Ignition coil
-Battery
-Smog pump
-Battery terminals
-Thermostat
-Temp sensor
-Air intake sensor
-Checked and cleaned ground going to battery
-Fuel regulator
-checked injectors and none leaked
i pulled off the distributor cap and cleaned the contacts and it still having a hard warm start. I don’t know where to turn and know there has to be someone smarter than me or has ran into this issue themselves.

you can hear the starter engage but it won’t crank at all. The lights dim in the dash and battery drops to 9-10 volts on the gauge. It does not turn over at all. After about 20 minutes of letting the engine cool down it fires right up.

Hi Alfred. Please give my regards to Bruce.
I had this happen once when my starter cable insulation had deteriorated and was grounding to the frame. It was causing a dead short whenever I tried to engage the starter.
Once I figured it out it was fixed very easily by replacing the cable.
