My 1987 Westfalia has a 1994 OBD-1 EJ22/25 Frankenmotor
(50k+ on the conversion done by 523Rods)
I have a strange starting issue;
- Normally the engine starts right up (just a few seconds of cranking)
- A few times now it either takes a long time?or won't fire up at all
- Still cranks perfectly?normally (high torque starter running fast)
- Also, occasionally?(and it seems related), 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
- there are two relays (starter and Ignition) next to the ECU under the seat and one or both seem to be the ones doing this
Ideas?
Thanks,

开云体育Good morning Mike.Sorry to hear about the issues you’re having with your conversion. I can’t speak to the starting problem but I will speak to my suspicions around your relay clicking. When your ecu test/memory connectors are connected you would experience the Subaru engine/ecu going through a “test cycle” repeatedly. ?When living in the donor vehicle you would hear the radiator cooling fan turn on and off, your relays would click, and other systems would be tested for diagnostic purposes. Check the 2 little plugs to be sure they are not connected. ?In fact, neither the green plugs (test) or the black plugs (memory) ?should be connected for normal running. Here are the obd1 pin outs at the ecu….
Here’s what the connectors look like while still in the donor Subaru vehicle. ?Your connectors location varies, but would usually be close to your ECU.

Mike,
A few easy ideas:
1) Put a volt meter across your battery and see what the voltage is when cranking. I’m not sure what the minimum voltage would be here but seems like a logical first step.
2) If you have a simple way to put a fuel presssure gauge on your fuel system somewhere - check to see if you’re pressure is low. Also be sure the pump is cycling to pre-charge the fuel system when you turn the key to the on position.
3) Did you make any changes before you noticed the issues that may be a factor?
?
Good luck!
