The fuel pump went out on this van, I installed a new one started and ran real ragged, I found if I wiggled the ignition. Switch it ran fine. Okay, switch is bad, replaced switch now it wont start. Checking the fuel pump again with a pressure gauge on the fuel rail I have 55 lbs. Of pressure. No start, if I spray starting fluid in the intake it fires right up, that tell me the ignition. Circuit is working. What am I missing? Thanks in advance for your help.

That is strange have you tried plugging in the old switch to see if it starts? You could have gotten a new bad switch. It is getting more and more common for new parts to be bad.

Otherwise there may be a problem with the ignition cylinder or ignition housing.

I took the old switch completely apart and the area where the ignition. Gets its power was almost gone. So there is no way to reinstall it. However if it starts and will continue to run on starting fluid, and there is fuel pressure why wont the engine continue on its own?

I suspect that the fuel injectors are not pulsing and letting fuel in. How did you checked all the fuses?

Well gentlemen, I had a brain storm and decided to see the actual fuel flow so I pulled the pressure gauge off the hose and pumped some fuel out of the tank, and to my surprise it was a dark yellow and stunk. How about a tank full of bad gas? Pumped it all out and installed fresh gas and low and behold it fired right up, on the low side now I have two dead cylinders, now to see if it is plugged injectors or dead plugs. Thanks for all the advice. Who would have thought bad gas?

Yeah bad fuel is a real pain to diagnosis especially helping through the internet. I am glad you found the bad gas. Keep me posted, I have seen bad gas that had sediment that clogged up injectors.
