Anyone in Michigan with OB CIS knowledge?

I live in Charlotte, MI and am having fits still with my 79 OB Euro...will fire on fluid so I know it's got spark...checked timing...seems good, just wondering if anyone in the area has knowledge on the CIS system and may have some time to help me with some hands on...appreciate the help. PM me here or on Rennlist, I have the same name on both.

Thanks,
Josh

Have you verified the fuel pump is running, can you hear it when you turn on the key?
Have you screwed a gauge on and verified that the pressure is over 35 psi (38-43)
After this have someone crank it while you listen for the injectors and at the same time I like to hold my fingers on the injector to try and feel them clicking.

I am betting that one of these things is not happening.

BTW let it be know that I would never ever ever use starting fluid on a gas engine

Try this to verify that it is not getting fuel as starting fluid can light without spark.
Dump 1/2 a lid of gas (from a spray can) down the MAF [remove air filter and dump it in the hole]
do not touch the gas peddle but crank it and see if it fires and runs for a few seconds.
If it dose, you are not getting fuel.

Mac,
1. I verified that the fuel pump is working when the key is turned on and also while cranking.

2. as far as screwing a gauge in, I don't have the CIS gauges and do not see a good location to tap into.

3. as to the injectors "clicking" I don't remember that the k-jet style injectors "click" they are not electric and as far as I've read with a constant injection system, all they are really there for is to atomize the fuel for the fuel/ air mix. If I am mistaken I'm sorry.

I will attempt to check the fuel pressure from the FD when I get home today.

Thanks,
Josh

Yea, CIS don't click and do require high pressure (I think higher than you are talking about Brad). I think there are two pumps for CIS car (well most of them, but I think you need both in a CIS car, but don't get me lying on that one).

Thanks James, I have heard that the early cars were hit and miss on the one or two pumps, some po earlier than me did the in tank delete...I may just need the bigger single pump...I heard that Andrew Olsen had intank pump issues so I really don't want to go back if I don't have to.

Thanks again,
Josh

You are right Josh, sorry. (bangs head)

section 25-6 of the WSM has a control pressure "warm" 2.8 - 3.2 bar
without vacuum
and
system pressure test value of 5.2 - 5.8 bar

Fuel Injectors opening pressure is 3.0 - 4.1 bar

here is a link to the manuals
