Why is my fuel pump not picking up?
Since tapping the relays created a “possible” start, it sounds like a relay may be at fault. The DME is a dual contact relay and one could be picking up but the other doesn’t. If after the Clark’s Garage procedure you don’t get the fuel pump to start, you’ll need to check the wiring from the relay to the fuel pump itself.
How does the fuel pump work in a car?
It gets power under either of two conditions: 2) engine speed sensor signal reads over 300 rpm or so with the key in the run position. The idea behind doing it that way is that in the event of a collision, the engine will stall and power to the fuel pump is cut off. The fuel pump does not cycle; it runs continuously.
Why do I need to borrow a relay for my fuel pump?
If the fuel pump kicks on using that procedure then you may need to borrow a known good relay to test your circuit. Since tapping the relays created a “possible” start, it sounds like a relay may be at fault. The DME is a dual contact relay and one could be picking up but the other doesn’t.

When to replace balancer shaft on Porsche 944?
Replacing cam drive and balancer-shaft drive belts at 48,000 miles or four years is vital to avoid a blown engine; the water pump should also be checked and replaced if in doubt. On the twin-cam S/S2, replace the hydraulic tensioner and the (mid-head) chain that takes drive from the exhaust to inlet cam at least every 96k miles.
What kind of suspension does a Porsche 944 have?
Twin Lanchester-type balancer shafts gave the big, powerful ‘four’ great smoothness. It was installed in a flared-arch 924 Carrera GT-like bodyshell with 924 turbo suspension and brakes, becoming an instant hit.
