WE had a 1998 Explorer that cranked good... good spark.. good fuel.. and would not start... There was a SENSOR at the front of the crank shaft that basically told the spark when to occure... SENSOR was bad..... similar to being OUT OF TIME.

I would give it a shot of starting fluid. If it sputters or starts then you know it is fuel causing the problem. ------------- 1957 WD45 dad's first AC 1968 one-seventy 1956 F40 Ferguson |

| fuel presure needs to 60 to 66 psi while cranking check for injector pusles , if that checks out move on to the distributer they seem to go to crap on those |

I worked on them back in the day and if they dont have a minimum of 60 pounds of fuel pressure they won't start. Sometimes you could put a battery charger on them to boost the voltage to get them to start but that didn't work all the time. ------------- If you choose not to decide you still have made a choice. |

Sorry for not getting back quieter but it turn out to be fuel pump and he let the gas tank get so low that it also suck up some dirt or something and now cly 1& 4 are dead so need to replace the spider injectors now, I told him 100 time that he couldn't let the gas get down past a 1/4 tank because the gas kept the fuel pump cool so now he is walking or relying on so friends to get around until he does enough thing for me to earn the money that is need to fix it. I'm hoping it's a life lesson for him. Again thanks for all the comments. |

Got a Grandson who is kind of in the same boat. Told him I'd give him $$ and all he had to do was...... Haven't seen or heard from him since.
