Fuel Pressure (Electrical)

Turn ignition on. Locate fuel control module under left side of dash. Using a jumper wire, connect terminals "B" to "D". Fuel pump (located in tank) should operate. If not, check and replace fuel pump at tank, if necessary. Check fuel pump pressure. See FUEL PUMP SPECIFICATIONS table.

NOTE: Fuel pump controller terminal identification is not available from the manufacturer.

FUEL PUMP PERFORMANCE

Application	Pressure psi (kg/cm² )	Min. Vol. in 30 sec. Pts. (L)
B2200
Electrical Pump	2.8-3.6 (.20-.25)	1.1 (.53)
Mechanical Pump	3.7-4.7 (.26-.33)	.9 (.43)

If fuel pump operates, remove jumper wire. With ignition on, backprobe rear of fuel pump control unit. There should be 12 volts on terminals "A" and "D" only. If not, check ignition and power feed.
Allow engine to idle. There should be 12 volts on terminals "A", "B", "D" and "F" only. If voltage is missing on terminal "B" only, replace fuel pump control unit. If any other terminal did not test as described, check ignition coil (tachometer signal) and power feed.
