Hello all, OK so i have 92 4runner 3vze. Today i went ahead and replaced my injectors with flamethrowers injectors. I used the Diagrams on here to conform all my vacuum lines are back in place.

The problem i am having is the injectors are not firing. With the cold start injector in place the truck will turn over but die instantly. If i disconnect the cold start injector she just cranks with no turn over.

Please help. I have tomorrow off as well and need it running by Thursday.

Thanks again.

 

How do you know the injectors are not firing? Have you used a noid light (or equivalent) to detect injector pulse?

Is your VAF connected? Any codes?

You leave many questions.

 

Sorry scope i tried to cover it as much as i could. VAF is connected everthing is back together. I have used a mechanics stephiscope to listen and can not hear the injectors clicking. Any ideas what i should check i will get the volt meter out and test them as i crank as well.

 

just an update got it running. after tearing it all apart again i found that some of the stock connectors wires were exposed and touching after applying some new electrical tape to them and putting zip ties on all the connectors she fired up on the second go.

 

^--- Glad you found your problem.

 

Longshot is 4Rockin, hell yeah!

 

Check fuses and EFI relay.
