Iv got a 1987 chevy celebrity it will crank up good but idling is the probleb


How long since a tune-up? Can you check for applicable trouble codes? Your obd1, you should be able to check some codes, yourself, if there are any.
To check for codes, you use a jumper wire between the A & B terminals at the datalink connector. Then, turn key just till the dash lites come on, no further. Hopefully the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes.
The basics for a rough idle is to check for a leak of some kind, fuel--egr--vacuum leak. Also, check and clean the throttle body and idle air system, see if it helps? There could be other issues?

Looking at vehicle module which is a port and b port


If you are refering to the Engine Control Module (ECM) for your 1987 Blazer, there are two connectors. One is the "A/B" connector (24 Pins) and the other is the "C/D" connector (32 Pins). The letters represent the rows in which a particuler wire or wire connector can be found. For example, if the wiring diagram shows the wire to be going to ECM connector B4, The actual location would be in the 24 pin connector at the ECM and would be the fourth wire in the "B" row of connector pins. SEE DIAGRAM BELOW.

Hi, are you sure your fuel pump is running? I'm assuming you have the 4-cylinder 2.5 liter engine. The ECU and the injector are powered by the same wire as the ignition system. See diagram below.

I cannot locate the flasher unit in my 1987 chevy celebrity. Help!


Both four way and directional flasher are usually on the fuse block. Sometimes the directional flasher is separate and up under the edge of the dash. To locate the 4way, turn it on and find the item thats clicking. The directional flasher looks identical but won't be clicking.
