I have a 93 and it cranks but wont fire. Any ideas?

I figure its fuel or spark but dont know what to check.

 

spark if all it does is cranks but not fires, mine had the same problem a week ago, the assembly lube crapped up the plugs, i took them out and cleaned them and it fired right up. if there is no sputter or ANYTHING, it may be your fuel pump (happened in my stang 3 weeks ago) it turned out to be the switch to trun the pump on and off went bad. it kept cranking and cranking but nothing happened. if there is a sputter but the engine doesnt catch it will the spark

 

that's not alot of details, but there's a darned good chance that it may be flooded also... doesn't take much for that to happen

 

Check the plugs 1st

 

if its not flooded it could be the ecu or igniter

 

Let us know..

 

Mine flooded yesterday.



1) pull all plugs

2) Disable fuel pump (fuse in driver footwell)

3) crank untill all of the gas shoots out (may want to put a rag here and dont smoke while doing it )

4) Install plugs (prob should get some new ones, make sure you put the leading plug into the leading hole and trailing into trailing)

5) put pump fuse back in

5) crank and enjoy



*make sure your battery is good to crank for step 5, step 3 could have worn it down and you could just flood again if it doesent crank easy)

Mine shot a lot of white smoke, its just the gas burning up, nothing to worry about



this is what i did and it wrked really well, cranked on 1st try.
