Isuzu Trooper Fuel System
Problem is fuel delivery. Pump was just changed 2 years ago for $5oo. Don't want to go there again if I can avoid it(especially if that is not where I should be looking) spark and everything else seems good. However car will occasionaly drop its idle very low (for an automatic) and then stall out. Or on the highway it will starve and die if the engine revs to high (like the speed limit of 60mph) Or it will not start if I stop at a Starbucks for a coffee for 10 minutes after driving it 5 miles to get there. A friend took off the air cleaner and put some fuel down the "throttle body" and I cranked it and it fired up and I was able to keep it going for a while while the revs remained in the middle zone(like driving 30MPH while in drive)
- Now is it the fuel pump again
- Or possiblely a tube that connects to the top of the fuel
tank to relieve negative pressure so that the tank does not
collaspe inward (I have worked on foreign cars other than
this one with this vacuum break line)
- Or possibly something in the TBI I can check? to make
sure all is good there?
The fuel filter to the engine compartment is clean and has been changed.
Any experts on this machine?
