Egr

thanks...I unhooked the vacuum hose... I switched the vacuum hoses it did nothing...now it won't start...I changed the egr valve earlier and I just chabged my fuel filter thought that was a option....

I'm a go buy a new switch hopefully that fixes it

Yes I changed the egr valve and the egr soloneid switch for it....still haven't done nothing....now it won't start at all....I just checked schrader valve to see if it had pressure in the line and it does.....and it does....I just don't know now
