I have a 1994 Trooper (SOHC) with just 70,000 miles on it. I've done the general up keep on it like oil, plugs, air/fuel filters etc... Runs great and very few problems until latley. It's very very hard to start. In the last 2 months we've put in a new battery,6 plugs,PVC valve,wiring set,fuel filter,fuel pump,starter and fuel pressure regulater on hunches from a mechanic. It's still hard to start. To me it sounds like it's STARVING for FUEL. I now cycle the key about 10X's before trying to start it and after trying many times it will start and then runs like a champ. I'm into this about $1300 already and still the same problems. I just don't want my wife and grandkid stuck somewhere. What else could/should I try? Somebody told me a Oxgyen Sensor?, also that I may have a bad/leaking fuel injector? At the shop when they hook up the computer to it it says everything is OK, well that's because once it does start it's runs great. The computer does not show a bad code #, because when it starts it says all is well. Any ideas and/or help would be GREAT! THANKS!!!!
