Go buy one then look at your throttle body and find the part that looks like what you just brought. Its easy to install it has two small screws attached on the side of what used to be a carbuertor it is now called the throttle body in the middle of your engine,its usually on the drivers side of the throttle body.And it has a small wire harness that plugs into another harness.

94 tahoe blazer won't start getting fuel and spark


What testing have you done?
I looked at info for 94 blazer 5.7L engine.
Do you have spark, everywhere? Did you use a gage And check fuel pressure, with tbi fuel injection 9--13 psi. With throttle body injection you should be able to see fuel injector/s spray pattern, both fuel injectors. Even if injector/s spray pattern looks good, 5 psi won't start and run a v8.
Check for applicable trouble codes. My info shows your obd1, so you should be able to check some codes, yourself, if there are any.
You need air--fuel--spark--compression, proper amount at the proper time and it should start.

Hi Dale:
I'd start by checking the throttle linkage to make sure the return spring is connected and not broken.
If this is fuel injected the TPS may not be functioning.

Cuts off when give it gas


There could be other problems than this but if an engine dies or bogs when excelerated then it is a lack of fuel. This is either from an accelerator pump in need of adjustment or clogged fuel injectors ( which with your truck is the problem). with fuel injection as seen on nwer cars and trucks the Throttle positing sender (TPS) could be bad or in need of adjustment.

Haynes Manual 24071 includes wire diagrams for all components. On the injector you have a pink and dark blue wire both are hot and signal wires. The only ground in the system is on the fuel pump and sender unit. Diagram 12-26 in the haynes maual.

Rebuilding injection pump


What you are looking for does not exist outside Stanadyne. The GM service manual refers their own mechanics to send the pumps out for anything other than basic adjustments. Even the Haynes Diesel Engine Repair Manual, part no. 10330, gives no info on rebuilding or repairing these. They tell you to send it out as well. You might check out The Diesel Page on the net and you may find someone who has done what you want to do and can talk you through it.Good luck.
