 97 intermittent starting problem
I've been having an intermittent starting problem with my 97 explorer limited for about a year. It's the 4.0L SOHC. It started as happening about once a month but is now happening weekly. Basically, at random times it cranks and the engine turns over but doesn't start. Sometimes it takes 3 -4 times and others about 10 times before it starts but it always starts.
From some research that I've done here are some things that I have replaced.
1) battery, plugs, wires, fuel filter
2) IAC valve
3) PCM relay
4) Fuel pump relay
Any other suggestions would be greatly appreciated. |
