fuel question

Guys, I know this question is off topic for a chev group, but you guys seem to be able to come up with the answer to just about anything. I am helping a friend with a B2600 mazda that quit on him. We have replaced the fuel pump, fuel pump strainer and fuel filter. Fuel pressure is within specs going into the fuel rail. How do I check the injectors? The fuel pressure regulator is on the end of the fuel rail. Could that be the problem. It will start on starting fluid or if I pour a couple tablespoons gas in the intake and run until it burns that up. After doing this 2 or 3 times it will continue to run, but will not take fuel unless you accelerate slowly, even if you let it run until it is at operating temp. It is just like it is starving for gas. Any help is appreciated! Charles

Sounds like a faulkty wire running the injectors or something in the computer...

I am not having too much good luck with my FI engine so take my advise for what its worth.

Tell him to make sure he takes care with that head. I own a 1989 B2600i

4x4. The head cracked one time. The cheapest head I could find cost $1800. One of those rebuilt motors from Autozone costs about $2200 and that was without the head. They couldn't even get one. Maybe his truck is different. Something about the "i" after B2600 made it a different motor. Anyhow, I know not related to your question. Just a warning to Mazda owners not to let it overheat.

If it was mine I'd get the shop manual and probably check the injectors.
