I have a 4.3 cpi and am having a hard time starting. I have to press the gas and it still takes about 10 cranks. once it starts it runs great. It has 170000 miles and I just did a major tune up. I replaced the fuel pump about 2 years ago and I replaced the fuel injection about a year and a half ago. Fuel mileage is great. Any help would be appreciated.

hows the battery and alt?

they are fine and I am getting spark when this is occuring. so I know it is probably fuel related. I don't want to replace the spider again, that's
pretty expensive.

before you do that check you fuel pressure first. can you pull any codes? possible tps.

Did you change the fuel filter?

Make sure the fuel pump runs when you first turn on the key. It gets its power through a fuel pump relay. If that relay is bad, the only way the fuel pump will run, is to get enough oil pressure. So a bad relay will cause hard starting.

I have checked the fuel pressure and it's between 55-61psi. I am running out of ideas except for that pesky spyder? Anymore ideas before I take the plunge with the injection master piece?
