pull fuel rail and have gas how do I check to see if I have spark
Expert:  Chad Farhat replied 8 months ago.

find the ignition coil and pull it out and using an old spark plug at end of it then , you can lay it on the block and try to start , you should see it arcing ?

Expert:  Chad Farhat replied 8 months ago.

you can pull one of the spark plug wires , it will be under intake tight spot , but you can get to it, pull one cable out, stick a spark plug at end of it and try this way

ok this is what I did I shot a little brake cleaner in the air box and it fired up so its not a spark problem its a fuel problem can it be a bad pump that's not producing enough fuel???
Expert:  Chad Farhat replied 8 months ago.

is the fuel pump coming on , can hear prime for few seconds from the turn of switch from off to on, you should be able ti hear hiss for fews secs? does it

you mentioned fuel on rail earlier ?
