155 won't start. No signal to fuel pump relay

[Lille-Twinny]

Hi everybody. I've had some issues with my 155 lately. It has been stored in a warm garage for about 5 months. Just had a full repaint job and didn't want to use it in the winter with all the salt here in Norway.
Car: Alfa Romeo 155 1,7TS Skinny 95MY with immobiliser.

Anyway. I parked the car, and when I was trying to start it again, the startermotor was working, but it didn't want to start. So, after 3 attempts, I found out that the fuel pump isn't running. Checked cables on pump = ground on both.

Found the fuel pump relay right next to the battery, checked all relays. Everything is fine. Cheched that there's supposed to be a ground- signal from the ECU to the relay to make the pump kick in. Hotwired this relay and the pump is working like a charm and engine fired right up.
So, since I'm missing the signal from the ECU I checked the contact on the ECU. The wire from the connetor on the ECU to the fuel pump relay is not broken.
Checked the inertia switch under the seat. A bit high resistance on both cables 5 ohm and 8 ohm, so I hotwired in on the ECU contact directly with no luck.

Does anybody have ANY clue on this one? I can make the car work, but I'm a bit worried since my hotwiring on the relay makes the pump go all the time when the keys are in the MAR position. Normally it starts up and stops after 5 seconds or so. I don't want to drive that car. Because, in a crash the pump would just keep pumping fuel... The hotwiring I have done overrides both the ECU and the inertia switch.

Sorry for my bad english and explenation.

Somebody will come along soon and answer your question.But if not have you tried posting your problem on www.155.org? That site is just as active as this and they only deal with the 155. Hope you get it sortedCheers Steve

Thanks again. I'll wait a bit and search on the forum there first, and then perhaps post it there as well..

Recheck the relays at the battery check that they are making a connection and rubb off an corrosion on the terminals and the car should start. This is a common problem on the 155

Hi. Thanks for your tip. I've tried to rub off all corrosion, but it's still the same. The ground signal from the ECU (witch is the signal to the relay to start) isn't working. Tested the connection and this is fine. Ohm over the contact from ECU to relay box.

Hi relays next to battery had this problem on 2 different 155 in the last year

Hi. Maybe I have to check the relay box a bit closer then... Do you know where the fault is exactly?

Thanks for the tip.

I was luckly had some old relay that had been in a old fuse box from inside a car. Replaced the relays and it started. The other car while the engine was turning over we tapped to relays and it started.
I think the relays stick inside.

No, the relays is working properly. They're all the same and I've swapped them with eachother. I have also tested the relays by putting 12V directly on to the connectors. No fault there..

Crank sensor? ciao daz

Can't be CPS if it runs after the pump relay is hot wired....

..common problem is the blades of the connector sockets push down inside when you insert the relay so it's not always obvious it's not making contact.

Ohh, great tip! I haven't thought about it. An absolutely great suggestion. I'm going to check it this weekend. Thanks a lot!

Yeah, that's right. But my browser kept redirecting me to a webring. I found the forum and I've registered there too, but I'm not autorized to post anything yet...

I've just given admin a nudge......they have to wade through a lot of spammers.....

[alfa.chris]

Richard has nudge them and bazza has sorted it

Thanks to you both, Richard and Chris I'll post it there as well since I've been approved

I've seen speedy has posted on it the 8valve skinnys don't have coded keys
