JesusLady Posted November 11 Share Posted November 11 (edited) I guess that's what I'm looking for. Replaced frayed timing belt but "the timing marks are so faint." The uncertainty makes me question. Fired right up after timing belt/water pump kit was installed, but when all was reassembled, car misfired then would not start. Fuel pump suddenly not priming and fuel guage not registering. "Let's buy a new fuel pump" but I wonder if it could be the main and/or fuel pump relays? Fuses? Ground wires? Please help, I've been told engine damage occurred when timing belt frayed but that's not possible (SOHC). My hunch that it's is an electrical fix has been pooh-poohed.

573417h Posted November 12 Share Posted November 12 Hi, I suspect a sensor could be incorrect, IE injector plug on CAS or similar. however, since you have indicated fuel I'd start there: - Ensure there is enough petrol and if in doubt put another 20L into it... then check to see if petrol is getting to the rail/front filter, if it is you can assume its not petrol related If its not... then hardwire the pump at the plug to a battery to see if its pumping etc, then you can start eliminating things that make the pump run ie wiring/relays. If it has fuel getting all the way to the rail/filter, then id check if it has spark, if it doesn't have spark then you can start trying to figure that why. If it has spark and fuel, then id compression test it and go from there.... 1 Link to comment Share on other sites More sharing options...
lmdew Posted November 13 Share Posted November 13 Well, since you said "Fired right up after timing belt/water pump kit was installed, but when all was reassembled, car misfired then would not start." First thing I'd check would be the T-Belt. Make sure the timing is correct! Yes you should hear the fuel pump run when you first turn on the key for a few seconds. Subaru fuel pumps are much better than aftermarket pumps! You can just put a little gas into the intake and see if it fires up to check and see if it's Fuel or Spark. 1 Link to comment Share on other sites More sharing options...

All of my auto 'experts' have started playing dumb the closer we get to showing it's an electrical issue and proving it doesn't need a new engine. I also suspect the timing belt is on wrong I have most of the tools, I'm about to do it myself. Link to comment Share on other sites More sharing options...
573417h Posted yesterday at 12:14 AM Share Posted yesterday at 12:14 AM i would check the cam angle sensor just to make sure its doesn't have an injector plug on it... and vice versa, if it doesn't then sort the cam belt.. 1 Link to comment Share on other sites More sharing options...
