Could be the main or fuel run relay located in the compartment under the luggage rack, passenger side, main relay also, fuse for the fuel relay 8amp. Electronic Control Unit is also located there.

Could be electrical, Hook up a timing light, three leads: Power, Ground, and one that goes around the wire to #1 cyl. Turn the engine over and see if there's firing. Note: u can check all 4 spark plugs this way.

Fuse lead goes to pin 30 of the fuel relay, u can jump 30 across to 57 and check for the pumps running, if not, change-I suggest both relays, main and fuel run relays. Both pumps get their 12v DC from the fuel run relay, both should be running when you switch ignition switch to on, then a tachymetric signal is fed from the coil to the relay to keep it running.

SOURCE: 92 spider reads 0 at oil pressure gauge but no light illuminated

buy a cheap manual oil pressure test gauge from a parts store, not the kind of guage you put under the dash but a tester, they come with different fittings for may app's, they are about $20, being sure of the pressure is worth that, if the pressure is ok then most likely the sending unit is defective.

I Think it's just conincidance. Sainsburys fuel is checked independantly by Trading Standards and a private company. Both turn up unanounced. Plus there is a warning in the stations if water etc. is found. This shuts of the fuel from that tank.

SOURCE: 1986 Alfa 90. 2.5V6. Engine cuts out while driving.

Possible worn spark plugs causing unduly high Voltage which cuts ECU to protect it from arcing feedback. This problem generally produced during acceleration. Car usually re-starts almost immediately. Replace plugs - clean leads should be a fix if these are the symtoms

Make sure to check the fuses, most of the time when this pump goes bad it blows the fuse, and fuses sometimes get corioded and dont make a connection take a look at the fuse box.

1986 alfa spider cranks but won't fire. Battery charge was less than 11.0V, this would cut off fuel injector system, and that occurred. With charged battery, engine cranks but no fire. Ideas??


The car has 2 fuel pumps. One in the tank (accessed through the trunk) and one under the right side of the car. One of these might not be working.

1990 alfa spider car will not start, looked at the fuel gauge & it seems does not move ( at zero) there's fuel in the tank. but I noticed fuel indicator light does not come on when I turn the key....


The float/sending unit inside your fuel tank has gone bad. It can be replaced, but will likely require dropping the fuel tank. The replacement itself is rather simple and straightforward, but removing and replacing the tank is messy, hazardous, and better left to a dealer or professional mechanic. You might consider using the odometer/trip meter to estimate your fuel usage.

There is a fine mesh screen sock on the pickup tube in the gas tank, replace that. It will collapse and starve the fuel pump, but not all the time.

your evaprative emissions could be purging into the engine at that point too, giving too rich a mixture.

here's what you are referring to:

ISSUE: A reduced power, hesitation, stalling at low vehicle speed, idling and/or a no start condition may occur on some vehicles in hot ambient temperatures and/or high altitudes. In addition, a no start may result while the engine is still hot and the vehicle has been parked for a short period. A stall may also occur when moving the vehicle from idle. This may be caused by a lack of vapor ports in the fuel pump, resulting in a vapor lock condition or internal high wear of the fuel pump components due to tank contaminants.
ACTION: Perform normal diagnostic routines as described in the appropriate year Powertrain Control/Emissions Diagnosis Manual (PC/ED). If the condition still exists after all diagnostics are followed, replace the fuel pump with a new turbine fuel pump. Refer to the following Part Application Chart for correct part usage. Also, replace in-line fuel filter with a new filter (E7DZ-9155-A). The new turbine fuel pump will reduce the possibility of vapor lock in high ambient temperatures. Refer to the appropriate model/year Service Manual for removal and installation procedures.
