2000 Blazer starting problems

Having major starting and keeping running problems......
So far have replaced fuel pump, fuel filter and cleaned fuel injectors. Car still does not want to start. Latest new part was mechanic replacing crank sensor. Still not starting.

Any ideas appreciated

Thanks

Get your codes read by Autozone for free.

Have you checked your plugs and coils?

Checked all hoses for a vacuum leak?

Replace Throttle Position Sensor?

same problem, more parts

put in a new crank sensor, now car starts intermittantly. Sometime it senses rpm, some times not. Driving us to drink.....not really but frustrating

any other ideas? how to check for wiring shorts??

I would do as Mark suggested with the Autozone stop. I wouldn't put a lot money into parts until I knew what the problem was.

Did you pop off the coil wire from the distributer? Them like to corrode and cause these types of issues. Is the cap and rotor in good shape?

You states sometimes it detects RPM. Did you verify this with a scan tool? If so, throw an ignition module at it as stated above.

usually starting and keep running problems are electrical. you have had good advise, but check __ ALL___ electrical connections. for me, 99% of electrical problems are grounds. or lack of one! 4 ingredients for internal combustion engine necessary to run:fuel-compression-firing(electrical)-timing. if any are missing, you will have a problem. ALWAYS!!!!!!! check the SIMPLE stuff first! good luck.
