The car is an 89 Formula 350.
With the engine running if I put my finger on the injectors I can feel them pulse. The problem is that some of them are pulsing really strong, some of them are pulsing not quite as strong as the others, and one of them is not pulsing at all ( or least I can't feel it).
Shouldn't all the injectors be pulsing with the same intensity?
Also, would this cause a cold starting problem, ie, long crank time.
Other than the cold start problem the engine runs fine.



thanks

 

Stock injectors should be about 16-17ohms on a meter. U would more thna likley find some of them at 5 , 2, 10 whatever, meaning the windings are going bye bye and u need new injectors.

U can also test them for leaking by priming the fuel pump and then blocking off the inlet and return lines and seeing how quickly it bleeds off.

Also u can pull the rail up (take the plenum off, etc) and lift the rail up and prime the system and inspect them for leaks.

Get some SVO Injectors(best for the $$$) and set the IC in the chip to 24 and go to town

later
