trouble starting
Ran into a couple problems. 1st my map sensor connector was broken. Replaced that. 2nd temperature sending unit sensor also broke. Don't know how, but also replaced that. And now my car doesn't want to stay on. It will stay on for about a second then die out. Before that she ran great no problems at all. Once I replaced those parts she started acting up. Also before it started giving me problems it sounded as in it was sucking in a lot of air then that's when the dying out problem started happening? Any ideas to what could be the problem?

Re: trouble starting
Two problems here:
1) You didn't even mention what kind of vehicle this is. Probably a '95 Z28, but still...
2) This is the OFF-TOPIC lounge....

Re: trouble starting
Now that it's moved:
Are you sure you got the MAP sensor pigtail wires connected to the correct harness wires?
Which coolant temp sensor did you change - the one in the water pump housing for the PCM (2-wire sensor), or the one in the driver side head for the gauge (1-wire sensor)? Did you get the correct sensor?
Shoebox has the info for the PCM wiring on a 95. Here's the page for the MAP sensor and the coolant temp sensor in the water pump housing:

Best thing to do would be to scan it for codes. Here's a link to free 94/95 scanning software:

Re: trouble starting
The temp sensor in the head only drives the gauge, so it will not have any effect on the engine running. The one in the water pump (which is for the PCM), it could effect how the engine runs. Often, parts houses give out wrong sensor for these and/or they don't work right. The correct ACDelco ones seem to be the best bet.
Observation of operating parameters might help lead you to a fix.
