Engine swap i have a 97 chevy blazer LS 4.3 vortech-i want to put the motor from the 97 into a 95 chevy blazer LS- is it possible ?

Did you reset the security and immobilizer?
Did you fit the ECM from the Blazer into the Silverado so it can manage _that_ engine?

Swapping engines between the same model has dangers, but different models, not sure. A quick search shows one may be a 4.3 and the other a 6.0?

You are going to need to Swap ECU also, They are not interchangable

I had to change my wiper motor on my 97 blazer. The relay should be in the fuse box, that is under the hood.

Yes, the engine will swap fine, for the vacuum lines Go to Autozone.com, become member, will give you repair manual,location of parts,diagrams.

Remove the fuel pump relay and replace it with another relay from a nonessential slot (i.e. wiper relay). Just make sure they are the same first. This will determine if the relay is the issue.

try autozone.com repair manual section!!

the first cylinder on top dead center put the distributor rotor should be positioned first cylinder.

There are several engines that will fit the 2.2l Ecotec, 2.4L high out put motor, and I have actually seen a chevy cavalier that has a 3800 V6 in it if you want to go all out but in most cases sticking with the ecotec motor or the 2.4 High Out Put motor would be best they are two of the best motors for these cars and since the Sunfire is basically the same car as the cavalier almost any thing motor wise is inner change able between cars depending on the motors i own an 2004 chevy cavalier LS sport and a buddy of myn has a 2004 Pontiac Sunfire and both have the 2.2L Ecotec and are both Manual trans and even most of the interior parts are the same except for some of the dash board components hope this helps you out
