... I suspect injection issues...
- Symptoms started without warning
- Cold temps 30 degrees or less
- Blazer sitting for a couple days without being started
- Fuel pump runs for 2 seconds when ignition is on and stops correctly
- Plenty of spark
- I don't know the fuel pressure
- About 96K on the clock
If I mash the throttle to the floor I can get the engine to start and it behaves like its way rich, so I'm wondering about a leaking fuel pressure regulator or something, though all the searches I've performed seem to discuss CPI and this is an SFI (SPI?) system I believe.
Once started and running smoothly it will the restart without issues until sitting overnight. Not 100% sure it's temperature related because this was noticed only yesterday.
I'm not fond of bringing vehicles to a mechanic unless I'm at the end of my rope, so advice as to procedure is very welcome!
Thanks,
Jeff
