1988 wrangler 4.0L auto won't start.

Your map sensor is located in your throttle body and yes it can do that

if it shuts off while driving and will not start back up for at least 10 minutes, then it may be the crank sensor doing this. is check engine light on! if so get it scanned to find problem code. if no scanner, auto-zone will scan for free. if light is on. CPS symtoms are: car dies and won't re-start till it cools down, or won't start at all. good-day ! crank sensor timing will be out of sync. it controls timing and sends info to pcm.

Some thing in the instrument panel has shorted out or the wire from the fuse to the panel., pulling to many amps. If you could do without the panel for two days you would find out if it's the panel or the wires before. Electrical problems are no fun. I'm into a Ford that I just got running (second day) And there are still problems. (stupid computers). For the wires a good place to start is behind the fuse panel

After for setting for so long it is possible the pump picked something up and it clogged the injector.

Many cars have the cooling fan on a thermostat or time delay, to allow it to run for a short period of time after the engine turns off, to cool the engine off. You may have just never noticed it before. So I wouldn't worry about that.
Your real problem is the blowing fuses, apparently you have a short somewhere in your wiring. Putting in bigger and bigger fuses is a great way to set fire to your wiring harness. It's possible that the wire is pinched or chafed somewhere, and perhaps when you hit a bump just right, it touches and shorts.
You may have to take this to the Chevy dealer or a GOOD independent shop to have them chase it down. Unless someone out there knows exactly what this is, it could be a tough one to find.

Is fuel filter on backwards? This is common in fords cuz ppl run tank dry then switch tanks so all rust sticks to bottom of strainer some gets through. Start there look for arrow on side o filter point toward front

Hey Mudkicker,

Who ever thought of putting an electric fuel pump inside a tank of gas........

Check your other gauges for accuracy. They do that when a ground is loose.

Check the wiring from the fuel tank along the longitudinal frame for frays and shorts. Plugs are secured.

Under the hood, passenger side, check the fuel pump relay. Switch it with one of the others to test it.

Bring the vehicle to an auto parts store. Ask them to break out he code reader. Check for diag codes

Comment me back
Mike.

could b thermostat....when car warmed up check hoses from radioator if not hot change thermostat

ck fuel pressure
