I bought a gage today and it is about 40 pounds so I am sure that the pump is getting enough pressure. Could it be the timing? Ireally need to get this thing running so I thank you for any advise you can give me.

if you are only getting 40 psi of pressure you probably got a tbi pump by mistake.you should have at least 60 psi off the pump and probably close to 55 at the cpi.40 is way to low for a cpi,it could also be your fuel pressue regulator is allowing too much fuel pressure to bleed off.

well I have not replaced the pump yet soI think that the old one just went bad. Thank you guys for the replies and I will post with what happens when I replace the pump later today. If I still dont get enough pressure I will check the fuel pressure regulater. Thanks again guys.
