'98 Blazer cranks, difficult starting when cold
.... 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 |
