Richard S Posted March 11, 2008 Share Posted March 11, 2008 Can someone give me an idea of all the fuses and relays related to the braking system? I know the where the pump relay sits on the firewall. Others? Link to comment Share on other sites More sharing options...
Barney Eaton Posted March 11, 2008 Share Posted March 11, 2008 Unless someone has moved them, the relay on the firewall, closest to the master cylinder is for the ABS, the next one is for the booster pump. If you have a 1988 or early 1989, there will be a third relay, toward the passanger side, that is for the fuel pump. Then there is the fuse for the brake relay.HVAC fuse (10amp) powers the EBCMABS main relay fuse (30amp)Stop/hazard fuse #6 (20amp) feeds the brake switch and is grounded in the EBCM Link to comment Share on other sites More sharing options...
Richard S Posted March 11, 2008 Author Share Posted March 11, 2008 That's great. Thanks, once again, Barney. Link to comment Share on other sites More sharing options...
Guest steakneggs Posted March 12, 2008 Share Posted March 12, 2008 I don't think that any of the three on the firewall would be the fuel pump fuse because I removed all three when I converted my Teves and the car still runs. My manual contradicts itself saying that the passenger side one is the brake pump relay fuse in one diagram and the ABS fuse in another. I'm still looking for the fuel pump relay. There is one somewhere. Steak Link to comment Share on other sites More sharing options...
Ronnie Posted March 12, 2008 Share Posted March 12, 2008 Steak, The fuel pump can also be powered by a set of contacts inside the Oil Pressure sending unit. The car will take longer to start because it has to turn over enough to build oil pressure, then the fuel pump will come on and it will run.See the Driveability & Emmisions section of the FSM, page 6E3-A-28, Chart A-5.

jonlabree Posted March 12, 2008 Share Posted March 12, 2008 The fuel pump relay on a 90 is inside the console Link to comment Share on other sites More sharing options...
Ronnie Posted March 12, 2008 Share Posted March 12, 2008 It sure would be helpful if everyone would put the model of their Reatta in their signature line so we would know up front which model we are talking about. The model of the car is the number one question that comes to mind when trying to help someone out. It gets cumbersome asking the same question over and over again.I'm not putting anyone down... just wishing out loud. Link to comment Share on other sites More sharing options...
Guest steakneggs Posted March 12, 2008 Share Posted March 12, 2008 After a lengthy search in my FSM ('88), I found out that the fuel pump relay is on the firewall (like Barney said) and the fuse is in the relay center. I was kind of hoping that the electrical clusterfunk on the firewall was all Teves-related. I don't think the Steakmobile fuel pump is running off the oil switch because it starts easy.

Richard S Posted March 17, 2008 Author Share Posted March 17, 2008 Barney, are the HVAC and ABS main relay fuse both in the box in the engine compartment, or in one of the passenger compartment fuse centers? Link to comment Share on other sites More sharing options...
