no fuel from injectors 2 & 4
 

Last night I finally got around to installing MS. My car will fire right up but its only running on 2 cylinders. Every cylinder has a good spark and I checked my firing order and that looks correct. If the car is running and I disconnect injectors 2 and 4 it does nothing. The car still idles the same. I double checked my wiring and connections and so far they look ok. I still need to get my meter and check for continuity.

Anything else I should check?

you can jump a 9v battery to the injector and if it is good, it will click. Are these new injectors?

Injectors just came back from getting cleaned and flowed.

I would have said CA car, but shouldn't matter for 91. Email me your VIN (ben at mazmart dot com) and I'll run it through EPC on Monday.

Just checked the continuity from the injectors to the MS connector and it fine. There is a yellow wire that powers 2 injectors and a yellow/black wire that powers the other two. I'm thinking there is something wrong with my MS.

I saw somewhere a couple of days ago that 2 and 4 are batched. Probably something in your MS.

i can has msq?

Cleaned the board, reflashed firmware and map, started car again. I get fuel to all cylinder now but I'm fighting some other problems. I'll keep you posted.

Thanks!
