Repair and operation of the car

Check of usefulness of functioning of the bomb / pressure of fuel of fuel

General checks

ORDER OF REALIZATION

1. One secures available of a tank of gasoline of enough fuel. 2. One secures that the fuel bomb really works. Ask a spectator to include the ignition, having become a key in the position of in, – in a gasoline tank the characteristic sound of the bomb of work has to be heard during two seconds. The work bomb is quite audible for an open mouth of the tank of fuel. If the bomb is not lit, I pass to the check of his electric chain at the same time (9 sees the paragraph).

The checking of the pressure heads the characteristic of the bomb of fuel

ORDER OF REALIZATION

1st. The special manometer adheres to the union of experience in the filter of fuel (companions see illustrations). 1b. The transitional mouth is rolled in an opening under the installation of a pin of service (I model for 1996 for the question), or instead of a hollow pin of the connection of nipple (I model from 1997 to question) (to see the pressure that Falls in a system of provision of power). 2. Turn the key of ignition in the position of in (without beginning the motor), trace that to / in him was put out. The fuel bomb is going to be lit for the couple of seconds – the pressure in a system of provision of power will increase (check the indication of the manometer) and to be stabilized. 3. The motor begins and heat it in the only turns up to the temperature of normal work. Compare the indication of the manometer to Specifications demands. Now desconecte a hose of vacuum of the regulator of pressure of fuel – the pressure will increase immediately, besides to the value stipulated in Specifications. 4. If in the hose of vacuum been connected with pressure it exceeds the standard, through the bomb of manual vacuum (companion to see an illustration) creates the depression of 305÷355 mm of mercury to bottom in the regulator. If the pressure falls, check the usefulness of the functioning of a fountain of depression, otherwise substitute the regulator. 5. If the results of the measurement of the pressure exceed the limit of the admissible variety, they carry out the next checks:    a) If the pressure is excessively high, check the usefulness of the offer of the regulator of depression (companion sees an illustration). The depth of the depression has of flutuar with the modification of turns of the motor. If the depression is present, check a state and passability of a hose / tube of the return of the fuel. If the repayable line as debit to be, substitutes the regulator.    b) With the excessively small pressure they substitute the filter of fuel, having excluded the probability of the violation of his passability. If it will not help the substitution of the filter correcting a situation, installing the door of closure in the siege between the regulator and the line of repayable fuel (instead of the door it is possible to establish a part of a flexible hose that can corset itself easily for claws or an armband). The motor begins and begin to blockade slowly the door / to hold tight a hose. If 2 increases the pressure above the value of 3,2 kgfs/cm, substitute the regulator (to see the Removal and the installation of the case of a regulator). 2 does not allow the rise to the pressure any more than 4,2 kgfs/cm. Do not hold tight the line of fuel in fact repayable to avoid the risk of his damage.    c) If the pressure remains excessively low even in the blocked repayable line, there checks the existence of holes an injector (injectors) of injection (to see Removal and installation of the road of fuel and injectors of the fuel of injectors of the fuel). Also check the usefulness of the bomb of fuel. 6. To finish check, pressure of heap (to see the pressure that Falls in a system of provision of power) and desconecta the manometer.

Check of an electric chain of the bomb of fuel

The information most detailed in the scheme of an electric chain of the bomb of fuel contains in the electric equipment of Front Side.

ORDER OF REALIZATION

1. If the fuel bomb in the moment of the inclusion of the ignition does not work (of a few sounds of characteristic of tank of gasoline they are not heard), check a condition of a lock of security of the main thing (PGM-FI) of the alternation of the system of the injection (to see the electric equipment of Front Side). Substitute the lock of security it had been beaten and a repeated check. If after the substitution of a lock of security the bomb begins to work, to check an electrical system of his chain of the existence of signs of the short circuit in the siege between the alternation PGM-FI and the bomb. 2. If the substitution of a lock of security does not lead to the restoration of the functioning of the bomb, check the usefulness of the offer of the food of the last one. Withdraw a rear seat and there secures the tension of available battery the capture of bomb of a covering of service of the meeting of the bomb / sensor of the consumption of fuel. If the food moves regularly, substitute the bomb. 3rd. If the bomb is not operated, check an outline of alternation PGM-FI. Ask a spectator to turn several times a key in the lock of ignition of the position of in the position of in and behind (without beginning the motor). At the same time look at the emergence of the tension of the battery in the alternation capture. The Civic models – the alternation is located below a carenagem on the right. 3b. The models Integra – the alternation is located below a carenagem in the left. 3 pages. In the ignition included the tension it will remove captures 5 and 7 (companions see illustrations). If the food does not move, check a chain to existence of intervals or short circuit (to see schemes of electric connections in the electric equipment of Front Side of the present manual). In some decrease of pressure of models of oil below of some value daily pay adjusted the switch of sensor of the pressure of works of oil like the valve of closure, blockading the supply of fuel – checks the switch of sensor and an electrical system of his chain (to see schemes of electric connections in the electric equipment of Front Side). The system that is antidragged supplies an immobilization of supply of fuel. The system failure will not allow to do the launch of the motor. Also check a chain of the alarming system that is antidragged. 4. In the moment of the useful offer of the food they withdraw the alternation of the check. A point of passage of wire joins the positive capture of the battery to the capture 2 nests of the alternation. 1 fuses the capture. Then through an ohmmeter they secure the available condutividade between captures 4 and 5. If the condutividade if it is going away, substitutes the alternation. 5. With the condutividade they join the positive capture of the battery to the capture of 5 alternations, establish the capture 3. Now the condutividade has to happen between captures 6 and 7 otherwise substitute the alternation. 6. If the condutividade happens, 6 gives the food in the capture, 1 fuses the capture and the condutividade checks between captures 4 and 5. The absence of the condutividade they substitute the alternation.
