Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.I would tart first with making sure the spark plugs are not fuel fouled which can cause a no start condition. If the spark plugs check to be dry and clean and you are sure you have good spark to them as well as proper fuel pressure and injector pulse then the next step would be to run a compression test to be sure you have proper compression. Check this for me and post back with the results and we can work from there.
Well as you know in order for the engine to start and run you need good spark to the spark plugs, injector pulse, proper fuel pressure and good compression. Have you checked to see if you have all of these?
Are you sure your scanner is Toyota compatible? The compression is on the low side at 120 PSI. What about injector pulse, have you checked it?
Okay, let me know and we can work from there.
Neaither one of these thing make any sense, so you saying it will run if you remove the injector fuse and with the fuel pump unplugged. Are you sure the engine is not over fueling?
Have you checked the actual fuel pressure?
