I replaced a heater hose that connects to the heater control valve, filled up coolant, drove it around the block and ran fine.
Parked it, replaced blower motor, now car wont start. Thinking I messed up the ECU or something down in the passenger footwell, but i never unplugged ECU and all connections appear to be tight.
Fuel pump doesnt prime when you turn the key, tried several different fuel relays with no success. Jumpered the pins, and fuel pump will run non stop without issue. Cranks fine, but still no start.
Pulled a plug to test spark, and no spark. Plug wasnt wet with gas at all, so injectors must not firing either? Replaced crank sensor with no change.
So I'm thinking it must be something down by ECU?
Could anyone point me in the right direction with what to start testing with the multimeter? I am garbage at electronics. Desperate to get this car running, any help would be amazing.
Thanks in advance.
