Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi there, I am Cam. Can I get your first name please? how much fuel did you put in the other day?
Currently if you pump the plunger on the fuel filter, does it get stiff or leak fuel anywhere?
Noel., good afternoon. IS there any chance you put gas in by mistake? IF no, can you try starting with someone pumping that plunger and see if that helps?
IT could be the fuel level sensor, yes. They are common for reading incorrectly in these. For now, even open the bleeder on top, pump a bit and see what fuel comes out. IF gas, drain your tank and lines/filter, fill with diesel and see. If its diesel, then do this test.
These use hydraulic pressure from the fuel system to operate the injector. SO a small amount of fuel is supposed to bypass to open the main part of the injector to make it operate. When these start to fail, this causes to much fuel to bypass and return to the tank. This resulting fuel loss will lower the fuel rail pressure and at a time when the pressure is needed most, during cranking, it takes longer to build the required 1450 psi to operate the injector. SO the test we do is this. Find the 2 fuel lines on the rear drivers side valve cover. Take the smaller one off and attach your hose to the metal pipe coming from the engine. Put the other end into the container and run the engine to fill that line. Then shut it off and remove the IGN 1 relay from beside the starter relay. If the engine will not start at that time, crank it to fill the line, then empty out the container and keep the line full. Crank the engine for 15 seconds fully and measure the amount of fuel that comes out of that line. More than 24cc means the injectors have failed and they need to be replaced.
That could be fuel related. Check to see if your oil is overfull. IF so, let me know and I can explain more.
