Thanks for all the great suggestions on the start problem I have on my EJ22
I have investigated several items and am looking to?next?steps
Background:
1987 Westfalia w/ 1994 OBD-1 EJ22/25 Frankenmotor w/ starting issue;
- Normally the engine starts right up (just a few seconds of cranking)
- A few times now it has taken a long time?or wouldn't fire up at all
- Still cranks perfectly?normally (high torque starter running fast)
- Also, occasionally, when I turn the key to the 'Run' position and don't go straight to 'Start', the CEL flashes On and Off repeatedly plus I hear relays clicking in the back
Update:
- changed the fuel pump relay and ignition relay
- installed new fuel pump and post- pump filter (no pre-filter on this van)
- main battery voltage ~12.2V (it's not new but I keep it on a NOCO maintainer); very heavy duty battery cables to the engine
- still have basically the same problem: starts OK much of the time; sometimes takes several seconds of cranking; sometimes CEL and relays cycle ON and Off several times if I hold in 'Run' position before?going to?'Start'. If I wait for the CEL?to stop cycling, then the engine starts pretty much normally
Next Steps:
I'm guessing the fuel pump is taking a few seconds to bring pressure up and that there is a fuel supply issue; hence:
- I'll put a fuel pressure gauge on the fuel hose to the engine
- I'll order a new fuel pressure regulator?
Any other thoughts?
I believe?I have most of the diagnostic equipment and spare parts (fuel pressure gauge, spare Bosch pumps, filters etc.) as I have diagnosed many Triumph TR7s which use (virtually) the same L-Jetronic EFI system as the original Vanagon wasserboxer; though the Subaru EJ22 behaviour is a bit different it seems (a pulsing fuel pump at start is normal???)
Thanks again for all your advice
