Got a weird problem I haven't been able to pin down. Had this truck about a year (1994 4.0 4x4). Morning and basically after sitting or cooling down it'll crank about 5 seconds or more before it fires up and runs great. When running it runs like new. Another intermittent issue is if I run to the store, come back out and start it 1/10 times it'll run rough like a misfire for a minute or until I blip the throttle.
Fuel pressure is within spec. Cycling the key/pump a few times in the morning doesn't help. I had it at a shop they ruled out headgasket/ and fuel related issues(fpr/injectors/ect. I replaced the ECT sensor and both o2's. Thinking crank position sensor possibly?
Open to any ideas or things to test/try.
Thanks!
