Hi,

I will chime in on what Dave Steven has said and for you to go for a new CPS.
I have used some from AIP Electronics with no problems. As I remember they were about $25 on Amazon. I have prime that makes them worth buying over E bay or other sites.
I bought three back in 2018 as I have just recently used my last one on my 1993.
I think I will buy a couple more, as for me, that’s a high failure rate.

As far as the fuel pump running for a second or so after turning the key on to the second position may not happen on the 1989 model.
It is my belief that the feature of pressuring the fuel rail over the injectors was not in place until my 1991 or the year before. I have never confirmed this production change in the ECUs.
So, don’t be surprised if that doesn’t happen.
Maybe someone can plug in better information on this thought.

There is a nice post on Art Benstein’s web site Cleanflametrap.com.
For the fuel relay itself yes, it is a contender to be the next problem as Dave has said.
As far as making the pumps run that can be forced by using a jumper wire in the drivers side fuse panel.
It’s a simple test as he jumpers the ends of fuses four and six together.

When it comes to the 240s, he has provided a lot of information to keep the cars on the road probably as long as air cooled Volkswagens engines without rebuilding them. 😊
It might have been there or on in some a post involving Art’s input about the priming mode.

I do pretty well at remembering important stuff but the details of how it’s in my head and how it got there isn’t so much like it use to be.
I’m pretty sure that everything I do or have done is not all of my own thinking!

Ours brains are always taking in data and storing it for a recall but more of it can be at the top to be readily accessible than the rest. But there’s a back up system is in play with our subconscious.
You will think of a solution and have no idea exactly how it came about.
Phrasing or tips from some past conversations, with others, just slide in.
The Brickboard or plain-ole’ networking has sped up technologies vastly.

I still can wake-up after a nights rest and when I have a thought about what I was thinking about the day before, an idea will jump out there.
This is before I have even walked outside, to see any clear blue sky! 🤔😊

Fixing up this car, to run again, will just take a few mornings! I hoping this for the cars sake! 👀
There is plenty of help and information out there but the effort will pay you back handsomely. 🤫

It may be the only reason I look as good as I do for my age, as I have a horn too! 😊
Gook luck,

Phil
