I have a 95 blazer and one morning the check engine light came on. So I went to a shop and the mechanic said that his machine wouldn't read the code. He suggested unplugging the battery for 10-15 minutes to reset it. I did and then had no problems for a month or two except it seemed to be getting worse gas mileage. Then the light came on again so once again I took it to a shop and had the same result wouldn't read the code! And now the blazer was having trouble starting on the first turn over. So I replaced the fuel filter. Seemed to help a little still wouldn't start on the first turn! Little by little the car took more and more attempts to start until we wore the starter out! So I replaced the starter. And rotor and cap. Now the SOB won't start at all! Waht can I do next?

Hello, my info shows the S and T series Blazer for 95 is obd11, v6. If my scanner won't communicate with the computer, I check pin 16 at the datalink connector for voltage. If nothing there, I check the fuse for that circuit. Power/aux fuse 7--25 amp, interior fuse box. Also use a gage and check fuel pressure. Do you have TBI fuel system or spider?

Since you replaced cap and rotor
are you sure its tdc on #1?
Is there a fuseable link?
I recently bought a f150 for my sons 1st vehicle( it was $400, the jason shell is worth 350 on craigslist)
had to replace the solenoid and was in a rush and I crossed the leads and had the + on the wrong side of the solenoid( no connection to all the links that had to have 12v. )
had no power to lights radio or anything
took me 12 hours to realize what I did
very frustrating
good luck

What is a good way to tell the difference between the obd1 and the obd11? I honestly don't know if I have a TBI or a CMFI. I see in the chilton that I purchased that both are put into this year of Blazer.

The cap and rotor were replaced by good friend when I was at work one day. After talking to him he is very sure that he put it in correctly. There is no fuseable link that I can find. In high school I replaced the solenoid in my dads pick-up twice because the first time I crossed the wires and the second time I didn't disconnect the battery first. What do you guys know about the relay switch in the glove box for the fuel pump? It clicks when I turn on the key? Is that right and there are two relays in there what is the other one for?

In the cross-over years, the diagnostic connectors could be a combination? Usually the ob1 connector has 12 cavities, the obd11 has 16 cavities. There might be a sticker under your hood that tells if your fully obd11 compliant.

Your engine code on the vin would tell if your cpi or tbi, W is cpi-- Z is TBI. Also with TBI, you see the injectors spray gas.
