I had to install a oil pump, intake manifold gasket, radiator hoses, and had valve cover off while getting painted today i finished putting it all back together and i have no spark. there is gas on my spark plugs and the car cranks, it seems weak but it does crank. I assume it would be the spark plugs or coil packs? Does anyone have any other suggestions or advice? I'm stumped ive taken the spark plugs out to let everything air out

 

No spark on any cylinder? Or just one?

 

On any cylinder it just keeps cranking and wont even attempt to ignite.

 

check the simple things first. like small ignition fuse inside car

 

Oil pump means you had the CKP off, the timing ccover off, and the TRIGGER wheel off. you put that trigger wheel back on yes?

2000-2005 trigger wheels are the same, and has no front side. Works both ways, so if its intalled, its correct.

2006-2009 trigger wheel is different, and can ONLY be put on in one direction.

You left the cylinder head on yes?

 

And i dont know if this makes a difference or not but, i have 3 denso coil packs and 1 aftermarket coil pack from carquest which is the newest. the one aftermarket and one denso coil pack will hold the spark plug in it when pushed in firmly. The other 2 denso coil packs do not does this mean anything and does it affect the performance of the oil packs

 

That is not your problem.

 

Not sure if this is applicable to the F20C coils. I've seen it on other motors. Check where the coils bolt up to the head. If that little pad around the threaded hole has been painted the coils will not get an earth.
