A few days ago I had replaced the injectors, as well as crush washers that I had taken off. She started just fine and ran well, for two days. After I had finished the replacement and had it running I had checked for vacuum leaks and such, all good. I've checked timing with a timing light, good there, I know there is pressure in the rail to the injectors and that the injectors work. Brand new spark plugs also tested just now. I am stumped. Everything seems to be in order but she won't fire. Any advice or help is appreciated thanks.

Edit: I have checked all fuses and replaced EFI main relay.

 

with both fuel and spark, it would at least do something. it should at least try to sputter to life.

-Check your air filter and make sure nothing crawled up and died before it. No air= no start

-spray carb cleaner in your intake and quickly close it back up and try to start it

-use a noid light (rent free from parts store) to confirm your injectors are being pulsed

also how did you test the spark plugs? are you getting a visible blue spark to them?

 

Checked the fuses with a Meter or just looked the old EFI relay was tested and found not working?

Just because your injectors were new does not mean they still work.

Just where did the new injectors come from so many knockoffs and just poor quality on the market??.

Why did you replace the injectors ??

Good Luck!
