no start

my 1993 caprice wont start. when i started looking for the problem i found that there is no fuel coming out of the injectors. since its tbi i put alittle bit of fuel in the trottle and it started up every time i turned it on, but after letting it sit for a while i tried to start it wasnt spraying fuel again. can anyone help???

check the fuel pressure at the test port ...low pressures / defective fuel pump, wiring, regulator, relay, injectors ,could cause this .

with your 93 I don't have the pressure spec's ...search the forum or your repair manual... on my 1996 it is around 47psi...what ever pressure it is it should hold to with in a few psi. if it drops rapidly then you must locate the cause ....usually the fuel pump...

Try the little things 1st!
1) fuel pump relay, fuse, and filter.
2) fuel pump pressure

1993 TBI - fuel pressure should be 9-13 PSI.
