1997 Explorer not starting HELP!!

[bigdreynolds]

I'm working on a 1998 Ford Explorer with the 4.0 SOHC . It keeps flooding the cylinders with gas . Changed plugs and it gas fouls them within a few seconds of cranking it .
Has spark.
Plugged NOID light into injector wire and it flashes BRIGHT , I've never seen one flash so bright . Thought it might be a stuck injector ..unplugged them all . Still real bright .
Thought maybe ECM so bought another one ....Same thing ???
Any Ideals ??

Is there a fuel pressure regulator on the fuel rail?

 

[bigdreynolds]

Yes there is

 

[dietz4ibanez]

Yes there is

I could see if it was bad it could be the result of dumping fuel.

Also, it could be the crank sensor too. My neighbors Ranger did the same thing, it would crank but no fire.

if the FPR is vacuum regulated, pull the vacuum hose. If fuel comes out, it's done.

Unhooked vacuum to pressure regulator ....it's good .
Crank sensor .. disconnected and no spark , plugged back in and have good spark , so I don't think it is either one of those .
Seems like injectors are squirting way too much fuel ??

Did it just stop running or was something done to the vehicle prior to its current running condition?

 

[bigdreynolds]

The girl started it in the morning to let it warm up , she went back inside and when she came out it had died . She tried to start but just cranked .

 

[Draenor]

My next guess is that the timing is off.

 

[dietz4ibanez]

I just don't see how it could jump timing. It's acting like a bad manufactured cap on the distributor.

I tore down Earl when it wouldn't crank, My 96 k1500. He has around 400k on him and I thought the timing chain jumped but it was fine. Ended up being a bad cap.
