ive got a 98 dakota 5.2 slt 4x4, that will crank and crank strong, but wont fire for the life of it. long story short ive thrown every single part at it that could make this happen (i believe) after kicking it down going about 35 the truck just shut off, no drama, no clunk, or anything, and havent been able to get it to fire ever since. i would really appreciate some help or input on it.

Thanks

edit: there are no codes whatsoever

 

Welcome to the forum.

Do you have spark? How about fuel?

 

no spark, coil is verified good, and ive got good fuel pressure while cranking.

Thanks for the welcoming.

 

OK. How about power to the coil? 12 volts steady? The ground is switched by the PCM.

Do you have a noid light? I'm wondering if the injectors are firing too. They all have the ASD relay in common.

 

i have momentary 12 volts when the key is first turned on, then when cranking it drops to 0. i think my ground for my asd relay is faulty, ive verified that the relay is working in a different vehicle. im thinking i may try to go across the positive and negative terminals for the asd relay to cut out that faulty ground and apply full voltage regardless. i hate digging through wiring bundles and ending up with a mess. and as far as the noid light, no; but im sure i can make one. im a broke college kid lol

 

ive got myself a dead battery thanks to the light on the interior of the hood that refuses to EVER turn off for me. dont need it; unplugged it and threw it across the neighborhood, ill let you know if i have any luck DakDan
