I just put a regular single cam dx in my civic, but it won't start up, it was running fine for a bit, but all of a sudden it wont start back up. it'll crank, but it sounds like its not getting fuel. its kinda got like a burbbling popin sound, like poof, poof,poof, as ur cranking it. lol. sorry. what could it be? fuel pump? injectors? spark plugs?

 

I would squirt some either down in and see if she pops on that. If so you then know its a fuel problem.

 

squirt some down in where?

 

down the air intake,i.e. follow the large tube back from the air filter,then dissconect it at the metal plentum where the throttle linkage is @... then open the throttle butterfly a bit then squirt some in.

 

jesus christ, really?
there are 3 parts need to run an engine. 1 fuel, 2 air, 3 spark
check fuses and what not.
does your fuel pump prime when you turn the key to the on position??

 

i would check you timing belt, kinda what it sounds like just take oil fill cap off and have some one crank, and watch for the rocker arms movin if you still have the t-belt cover that is, t-belts snap all the time its one problem i see quite a bit of and make good money off of fixing the bent valves

 

did you check for engine codes?

 

do you have good motor grounds similar problem happened with my old single over head turned out the tranny ground came loose good motor ground is essential

 

I agree with white civic hatch 88....it sounds to me like your timing belt was tensioned correctly and it skipped after running for a while. Hope it didn't hurt any vavles!!

 

Duh!!sorry, I meant WAS NOT tensioned correctly...
