To clarify, the engine cranks and starts. If it cranks but won't start until 4 or 5 tries, I would check the fuel pressure before and after the first attempt. The check valve in the pump may be faulty and allowing the fuel to flow back to the tank when it is not running. The pump only gets power for the first 3 seconds during crank time until the engine starts.

This truck doesn't use an expansion valve.

Hello, this is a very common problem for Chevrolet. Your wiper motor control module is bad. It's mounted directly onto the wiper motor. On some models you can replace the "pulse board" inside the control module. If not you need to replace the entire wiper motor control module. It depends on your level of skill and parts availability.

Please throw away that starting fluid. (Damages the engine more than anyone will ever know). Engines need 3 things to run: Fuel, Spark and Air. If you have a few minor tools check to see if you are getting a spark (or "current" through the wires using a tester for that), make sure she's getting fuel (clogged mini-fuel filter or maybe bad fuel pump/filter?) Air? That means you need to somehow ensure that when the #1 cylinder hits 'top dead center' that the valve for that piston is opening shortly and supplying the air. Otherwise ...no "putt-putt". Best of luck....

it may need to be reprogrammed. any good repair shop or dealer can do that. computers are too specific to just put one in form a junkyard and think its going to work correctly.

It could vary in prices depending on the placement and type usually high pressure hoses cost the most good luck hope this helps

Yes. System must be evacuated in order to open line to change expansion valve. After replacing valve the system must be vac tested for leaks and recharged.

120 psi is about the norm

Sometimes there is a valve on the right upper part of the doghouse if you are facing front. With hood popped look for a wing -nut looking valve. Test it a little and make sure its the right one before driving anywhere. Hope this helps.

sounds like you have a direct short in your starter, if you remove the starter you can take it to any Napa or auto parts store to have it bench checked, be sure and disconnect the battery cables first , and call ahead to your local parts store to see if they can do it,, Most do this for free, so check around

check the battery cable you will find a fusible link it looks like a barrol around the wire
use a test light on both sides of the fusible link

hope this helps you

were your heater control panel is at the back of the truck(if you have controls in the rear of the truck)is where the heater core is behind the the cover and the hoses connect under the van to the heater core.i`m assuming this is an 8 passenger van with carpet and rear seats.
