Curing Vapor Lock
« on: May 22, 2006, 07:02:10 PM »
I have a 90 Samurai with EFI.  After working with it I found that the starter was siezing.... I thought it was the engine locked up...... I completly reworked the electrical....... including a new starter.....
After a minute or two lock-up again.
I pulled the plugs (but left the plug wires close to the holes NOT A GOOD IDEA)
I turned the key and it ran freely... except for the 4 fire balls flying from under the hood.
So it seems that my Injector is free flowing into the intake.  Is this a simple injector replacement? or a more serious issue?
Any help appriciated.... I can't go without my Zuki for too long.

Un plug the inj. and see if fuel still flows out when cranking. If fuel does flow with it unplugged you have a bad inj. If fuel doesn't  flow then You prob. have a shorted ground side in the inj. harness or a bad Ecu.
