87 chevy s10 blazer 2.8 has power to all related components but no spray from injectors cranks but wont start

Use a noid light or other tool for checking the injector pulse is present.

If injectors have a pulse when the engine is cranked the reason there is no spray is there is no fuel pressure - fuse, relay, pump, wiring, pipework, filter. Water in the fuel tank is also a possibility.

If there is no pulse it could be crank or cam sensor, fuse, wiring or even the ECU.

Hi,

I would check n replace the fuel filter if needed. Also, it could be one of the spark plugs. Was it running before? Can you think of anything that happened or changed recently?

Make sure the battery has a full charge.

Are you missing anything besides fuel? Engine cranking visually check for spark at the spark plugs. Also, check for fuel injector pulse. If your missing everything, check for an rpm signal.

With the spider fuel system, start-up fuel pressure can be critical, around 60--66 psi. At the fuel pump connector, engine cranking, gray wire is voltage, black is ground. If good voltage and ground with no fuel pump action, have to suspect the fuel pump.

You need to check the crank sensor, this controls tthe injector pulse. If it will attempt to start with alternate fuel but not on its own, it sounds like the injectors arent pulsing, so your not getting fuel. Try the crank sensor first.

Click on the link for fuel pump relay, you can check the fuse. At the fuel pump, gray wire is voltage, black is ground.

Try spraying starting fluid in the intake,if the truck starts and continues to run,replace the cam sensor,if it does start,but dies,then replace the crank sensor,make sure the crank sensor is plugged up.

Thank You I did run the truck on starting fluid and it did die when I stopped the spray but didn't think of the crank sensor. I'm going to try that. Thanks. again.

Lets relearn the key to the ignition,turn the key on,and leave it for ten minutes,then turn it off,and right back on,do this a total of three times,and 30 minutes,see if it will start after doing this,let me know,I am standing ,well,sitting by.
