After a thorough investigation, it appears that the injectors are not getting ground to fire properly on my 1974 1.8L. Maybe it's an air flow sensor issue but not sure. All the other wiring seems to be okay. I would appreciate any thoughts from the knowledgeable folks on this forum. Thank you.

Jeff is the expert here so I'd start with what he recommended. Along those lines, have you tried swapping out the dual relay? I think you said you had the original metal can relay in your car. I'm happy to lend you a NIB dual relay for a test if you wish. You should have a back up relay anyway so you are not wasting money by ordering a new one. However for testing purposes I can get you one quicker than you'll be able to get from JBugs or any other supplier. Happy to put it in today's mail if you get back to me quickly.

I took your advice earlier this week and bought one per the SKU's and photos you posted. I won't get it until Wednesday, but my mechanic thinks mine if okay. I am also buying another resister pack in case mine is bad. I really appreciate your offer to send me a loaner! I will keep you posted as we solve this issue. Best to you. |
