My 3vze is running on cylindders 1,3,5. 2,4,6 are dead. What would cause this to happen.

 

We're going to need more info than this. How did you diagnose the cylinders? Any work done recently? etc.

 

cylinders 2,4 and 6 have spark. Can it be a fuel problem?

 

i put a new timing belt, distributor, and the truck ran good. I drove the truck around my block and parked it because it is running straight headers and i need to save money to get the exhaust done. I went to fire it yesteray and only one side of the motor is running. I checked spark on cylinder 2,4,6 and they were good. What is my next step?

 

Looking at the wiring diagrams the injectors for 2, 4 & 6 have a common feed, most likely your problem is they aren't getting power. It shows a white wire coming from the computer for those 3 injectors, either 2nd or 3rd pin from one end. According to the manual there should be 9 -14 volts at that pin with the ignition on. If you've got that voltage at the pin there's probably a broken wire somewhere. If not that's may mean a dead computer.

 

It is kind of funny but i changed the spark plugs and the truck runs great. I dont know if in the process i moved a wire to where it's suposed to be, but it works. Thanks for the help guys
