i have 94 B20 with a brand new battery, starter, and distributor..and i am not getting any spark..anyone have any ideas what it may be? thanks.

i also have new spark plug wires and spark plugs. the motor ran fine when i first swapped the motor, but all of a sudden, my starter went out, and after that it never started again. it cranks, but theres no spark. i checked fuses, switched ecus, and checked if any wiring harnesses may ahve fallen out. it gives this wired check engine light that keeps flickering.

wiring?

 

how would i go about checking to see if something is wrong with my wiring? and will i need a new engine wire harness if the the wiring is messed up? thanks

volt meter turned to continuity test. You might have a pin that popped out or you might have cut wiring. It might also be a loose connector or something like that.

 

thanks alot for the help man, i'll test it this weekend

 

Also check your grounds as well.

 

i'll be sure to check that too. thanks

 

okay, i fixed the spark problem, but now i seem to be having no gas, maybe my fuel pump went out? or maybe my relay? or maybe its another wiring problem?

 

get someone to put the ignition to the ON position but dont try adn start the car, open the gas cap and try and listen to see if you hear a winding sound coming from the fuel pump if you hear the fuel pump winding for about a second you're fine and its something else. if not then you need to check into the wiring, main relay, or fuel pump. maybe someone else can better define what I'm saying lol

 

just tried that earlier today, and i checked my relay, the relay is fine buti dont here anything from the gas tank, so i'll look into the wiring and the fuel pump

 

BUMP, this thread because a friend of mine is currently having the same problem, and I took a look at it this weekend...I checked everything that you guys talked about, swaped FP with my FP, and still nothing....I think it might also be wiring, maybe a lose pin or something...what about your dizzy, did you put it in correctly?

 

Change out ur PGMFI(Main relay)...it also controls sumthing else to..i forget..and i guess u can try changing ur fuel pump..and double check wiring...

yes check grounds i chased weird **** like this on a suburban for months. it was just going back and forth between no spark and no fuel pressure. finally found broken ground wire.

yeah the dizzy was put on correctly, i had to try 3 different ones before i got some spark. ive checked my grounds many times. and ive switched my relay with my homeboys car and still doesnt get fuel. so now ive narrowed it down to my wiring or fuel pump. thanks alot for the help guys

 

my baby just fired up today and shes running like a champ. thanks ALOT for all the help everyone.
