very common problem with these are the fuel pump, when i was a machanic i was replacing at least one a week on the s-10 blazers.

AnswerHey Rudy==Have the module chacked and check the pick up coil. Rotor, cap and wires could be a good investment. GoodluckJoe AnswerMake sure you aren't out of gas Answerspray some starting fluid into the air cleaner as close to the plenum as possible..if it starts then dies... more than likely your fuel pump is bad...replace the fuel filter too

++ANSWER++ Are your dash lights on? It sounds funny, but on the 1997 Blazer there are defects. I have one and unfortunately I have had to remove the cover under the steering wheel so I can pull or move the wires on the right hand side. You will know you have it right when the key is switched on, and you have dash lights. 97 Blazer will crank and crank, but rarely start. I sat for 1 1/2 hours one day. This is a faulty ignition switch, that needs replaced. If you go to the ntha complaint site you will se there are many 1997 Blazers with this same type of problem and others... Good Luck

ANSWER!!!!

Check your fuel pressure.

1.Turn ignition on do not try to turn the engine over.

2.under the hood find the purge valve for the fuel line. (indicated by a green cap)

3. press the valve in and see if it sprays out fuel. If this occurs its not your fuel pump. If no fuel sprays, there is your problem.

Will a 1995 Chevy 4.3 vortec engine work in a 1999 Chevy blazer?

From what I've experienced, up to 1995, they don't have a crank sensor and 1996 and later has one. It would reason that it would be a lot of work to get a crank fitted or cut and then install a timing chain cover to accept the crank sensor. Other than this. I would think it would work. Maybe look for a kit that would do this for you. Good luck. yes but would be different wiring
