The car will not start when it is completely cold (i.e. overnight) unless you give it a shot of starting fluid. Once it starts, it will continue to start fine unless it is again, completely cold. Any ideas?

That's a high pressure system and it requires a minimum of 55 PSI to run and starting cold is when the problem shows first. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional. tinjet New User Jun 30, 2010, 7:47 PM Post #3 of 4 (2189 views) Re: 96 suburban cold start issue Sign In Thanks for the info...is there a way to test the line pressure? I,m guessing that the the pump is in the tank and therefore a pain to replace.

If you don't have a gauge you could try cycling the key from off to on about 4 or 5 times (leaving it in the on position for about 4 seconds each time), then try to start it. If it fires right up you are in the 85 to 90% range of a bad fuel pump.
