I've been following a number of threads on this forum for a while. I did a number of searches for my particular problem but I can't seem to find the answer. I have the shop manual and I've spent about 8 hours testing circuits and looking for problems.
Here's the problem:
My wife and kids were going to restaurant and the van suddenly died leaving them stranded on the road. Luckily, a couple of guys helped move the van to the side of the road without incident. I had the van towed back to my house.
1) NO DTC or codes with the OBD II reader (with CAN codes).
2) I'm getting spark. I sprayed starting fluid in the air duct and the van started but quickly died.
3) key immobilizer blinks when I insert the key and goes out when I starting the vehicle.
4) new battery and I tested it- it is good.
5) I disconnected the quick-release couplings on the firewall and to the fuel pump assembly. I used my air compressor to blow out the line and the line doesn't seem to be clogged.
6) when I turn the key to on position (II), I can hear the fuel pump run for about 2 seconds.
7) I removed the fuel pump assembly and looked at the wire connectors and the assembly. I reinstalled it and I connected the fuel line going to the pump.
8) I left the fuel line on the firewall disconnected and again tried to start the vehicle. I wanted to see how much fuel the pump was pumping. When turning the key to start the van, not a whole lot of fuel pumped out of the firewall fuel lines (maybe a couple of ounces). I don't know if there should be more?
Here's the facts:
changed timing belt at 100K miles
no DSC or trouble codes on my Actron Reader
key start position II: MIL light comes on, stays lit for twenty seconds, and then blinks five times before going out.
In your experience, what would seem to be the most likely cause of the vehicle cranking but not starting (and again, suddenly dying on the road)? And remember, the vehicle runs for a couple of seconds when starter fluid is sprayed into the air cleaner assembly.
It would seem to me that the lack of fuel coming out of the fuel line would be due to a failing pump, a stuck or clogged fuel regulator, a clogged fuel filter (which is part of the fuel pump assembly )
Anyway, I appreciate your help.
